Charts enable you to present worksheet data in graphical form. When you create a chart, the worksheet data used to create the chart is linked to it. When the worksheet data changes, the chart is updated to reflect those changes. Excel provides many features for creating and formatting charts. The Chart Wizard leads you step-by-step through the process. You can change chart types, add elements to a chart (such as titles or legends), and format chart elements (such as numbers, fonts, and styles).
Excel also enables you to add graphic elements to your worksheet. You can import graphics from other programs, insert clip art objects, or use the Drawing toolbar to create objects such as arrows, rectangles, and WordArt. After you draw an object in the worksheet, you can edit, rotate, flip, copy or move, size, or add shadows or 3-D effects to the object.
You can use the data map feature to present geographical data from your worksheets in map form. Data mapping enables you to see the relationships between numbers and geographic features.
You can use arrows to identify chart elements that you want people to notice, such as sales data that is higher or lower than expected, or a specific trend that may be occurring in the chart data. Frequently, you may use a text label to include explanatory text, and you can draw the arrow from the label to the chart element. (See also "Adding: Chart Data Labels.")
Move an existing arrow by selecting it and then dragging it to the location you want. To change the length or position of the arrow, select the arrow and then drag the white square at either end of the arrow. To delete an arrow, select the arrow and then press Delete.
TIP: You can format the arrow by adding color, changing the thickness of the line, or selecting a different shape for the arrowhead. Double-click the arrow, then make the selections you want in the Format Autoshape dialog box.
(See also "Drawing an Object" and "AutoShapes.")
You can attach labels to data points on your chart, which helps the viewer interpret the data in a chart more easily. Data labels can represent the value for that data point or the category axis label associated with the data point. You can attach data labels to individual data points, a single data series, or all data points in a chart.
To remove existing data labels from a chart, display the Data Labels tab of the Chart Options dialog box. Then select the None option and click OK.
NOTE: umeric data labels display with the format of the corresponding cell(s) in the worksheet. To change a number's format in the chart, you can format its worksheet cell. If you want to format the data values directly in the chart, select the labels and choose Format, Selected Labels; then click the Number tab and change to the format you want.
TIP: You can add floating text in a chart to label an arrow or other chart elements. Select any nontext object in the chart, type the text, and press Enter. To move the text label, press and hold down Ctrl, then drag the label to the position you want. (See also "Adding: Chart Arrows.")
(See also "Formatting: Chart Data Series.")
Use gridlines to help viewers compare markers and read values in a chart. If you use the Chart Wizard to create a chart, Excel enables you to add gridlines as you are creating the chart.
You can add gridlines that originate from either the category or value axis, or both. In a 3-D chart, you can also add gridlines for the Z axis (chart depth). You can choose whether to display gridlines for major divisions on an axis or minor divisions (including points between major divisions).
To remove gridlines from a chart, display the Gridlines tab of the Chart Options dialog box, and then clear the boxes for the gridlines you want to remove.
TIP: Avoid using too many gridlines in a chart because they may make the chart confusing and difficult to read.
A legend explains the markers or symbols used in a chart. If you use the Chart Wizard to create a chart, Excel creates a legend by default, based on labels from the shorter side of the worksheet data series. If your chart does not include a legend, you can easily add one. You also can format a legend with border, pattern, and font selections.
You can move the legend by selecting it and then dragging the legend to the location you want. To resize the legend, select it and then drag one of the black handles surrounding the legend. To delete a legend, select it and press Delete.
TIP: To format the legend, right-click the legend and choose Format Legend from the shortcut menu. Make the selections you want from the Format Legend dialog box and then click OK.
You can add titles to help explain the data in your chart. Normally, you include a main chart title as well as titles for the category and value axes. If you use the Chart Wizard to create a chart, Excel enables you to add chart titles as you are creating the chart. You also can choose to add chart titles later or modify existing chart titles.
You can move the title by selecting it and then dragging an edge of the title to the location you want. To delete a title, select it and press Delete.
TIP: To format a chart title, right-click the title and choose Format Title from the shortcut menu. Make the selections you want from the Format Title dialog box and then click OK.
(See also "Formatting: Chart Titles and Labels.")
You can add a trendline to a chart to show the direction of the charted data and to make predictions. Regression analysis, a technique that describes relationships among variables, is used to create the trendline from the chart data. You can choose from among five types of regression lines or calculate a line that displays moving averages.
You can add a graphic background, similar to a watermark, to your worksheets. This feature can dramatically improve the appearance of forms and reports. A background also is a unique way of inserting a company logo in a worksheet without using a prominent graphic.
When Excel adds a graphic background, the graphic is tiled, or repeated across the full width and height of the worksheet. Tiling requires no additional memory for multiple graphics than it does for a single graphic. Excel provides some samples of graphic backgrounds, such as a brick wall or a deco design. You also can use pictures of your own as well as Web page backgrounds.
To delete a graphic background, choose Format, Sheet, Delete Background.
TIP: Most graphic backgrounds look better if you remove gridlines from the display. Choose Tools, Options; then click the View tab. Clear the Gridlines check box and then click OK.
You can add new data to existing charts, whether you created the chart automatically or manually. You can add a new data series to a chart, add new data points to existing data series, or change the entire range of data the chart uses.
If you are working in a separate chart sheet or an embedded chart that has been selected in a worksheet, you can use the Chart, Add Data command. You can use the Chart, Source Data command to edit existing data series or add new series. (See "Creating: Chart Wizard Charts" before you complete this task.)
NOTE: If the chart to which you want to add new data resides on a separate chart sheet (instead of being embedded within a worksheet), the procedure is a bit different. Select the chart sheet; then choose Chart, Add Data. Enter the Range for the new data and click OK. The data is added to the chart.
AutoShapes are ready-made shapes provided with Excel that you can add to worksheets, chart sheets, or embedded charts in a worksheet. These shapes are arranged in groups such as flowchart symbols, stars and banners, block arrows, and connectors. (See also "Drawing an Object.")
You can use AutoShapes to create an entire flowchart in a worksheet by adding flowchart symbols and using connector symbols or block arrows to connect the flowchart symbols. You can easily add text to most AutoShapes by selecting the shape and typing the text you want to insert.
You can move the AutoShape by selecting it and then dragging the shape to the location you want. To resize the shape, select it and then drag one of the handles surrounding the shape. To maintain the original proportions of the shape, hold down the Shift key and then drag one of the corner handles. To delete an AutoShape, select it and press Delete.
TIP: To format the AutoShape by adding colors, changing borders, or adding shadow or 3-D effects, select the shape and use the tools on the Drawing toolbar. For additional formatting options, right-click the AutoShape and choose Format AutoShape from the shortcut menu. Make the selections you want and then click OK.
You can change an Excel chart type to represent another type of data. You can change to any of the chart types that Excel offers--bar charts, line charts, pie charts, or special custom charts like floating bar charts.
You should use an appropriate chart type for the data you want to chart. The following list illustrates some common Excel chart types and explains their purpose. For more detailed information on all the chart types and examples of their use, search on "chart types, example" in Excel help.
NOTE: In some cases, data may be more effective when presented in a table or text chart. Don't overload your charts with too many data points. Combine data into logical units such as first quarter, second quarter, and so on to make your charts more effective.
Clip art is a collection of graphics and pictures that is available for use in programs such as Excel. Clip art enables you to illustrate ideas with pictures. You can use clip art in place of columns or bars in a chart to add interest to a presentation, for example. You also can use clip art to create a company logo for a company invoice or expense statement. Many of Excel's built-in templates include a placeholder for you to insert a clip art logo. Be careful not to overdo your use of clip art; generally one effective use of clip art in a worksheet is sufficient. (See also "Creating: Picture Charts" and "Template Wizard: Using Excel's Templates" in the section "Data Analysis.")
Many clip art collections are sold in categories like business graphics, medical graphics, entertainment graphics, and so on. To locate clip art, look for ads in the back of computer magazines, particularly desktop publishing magazines. You also may find clip art packages available for purchase at your local software store.
Some programs, such as Excel, include free clip art collections. You use the Microsoft Clip Gallery in Excel to easily access these clip art images. You also can find collections of clip art on the Internet and online services such as CompuServe, America Online, and Prodigy. (See also "Importing Graphics.")
NOTE: If you cannot access the Microsoft Clip Gallery, you probably did not install this feature with Excel. For more infor-mation on how to install the Clip Gallery, search on "clip art" in Excel help. Then choose "Insert an imported picture or clip art" and follow the instructions.
If you want to create a chart using the default chart type (normally a column chart) and place this chart on a separate chart sheet in the workbook, you can use the shortcut procedure listed below to quickly create the chart. Otherwise, if you want to use a different chart type or embed the chart in the worksheet that contains the source data, use the Chart Wizard to create the chart. (See also "Creating: Chart Wizard Charts.")
In Excel, you most often create charts using the Chart Wizard. Although the Chart Wizard steps you through the entire process of creating a chart, you can create the chart more quickly by accepting some or all of the defaults that Excel suggests. You can add a chart directly to the worksheet or you can create a separate chart sheet in the workbook. (See also "Creating: Automatic Charts.")
TIP: To move a chart, select it and drag an edge of the chart to the location you want. To change the size or proportions of the chart, drag one of the black handles along the borders until the chart is sized and proportioned the way you want.
Excel charts can use pictures as markers in place of columns, bars, lines, or as backgrounds. You can use this feature to make picture charts that draw attention and then communicate the information. When showing dollar amounts, for example, you can use money bags of varying sizes for each marker.
(See "Clip Art" for sources of picture collections.)
Excel enables you to add graphics to your worksheets by drawing objects inside the worksheet itself. The drawing buttons on the Drawing toolbar enable you to create ovals, rectangles, polygons, arrows, and even freehand objects. Excel 97 includes additional drawing tools as well as new tools to assist you with manipulating drawn objects.
By combining drawn objects, you can create all kinds of images. Drawn objects can enhance your worksheet reports, add annotation elements to your charts, and generally spruce up your worksheets.
You can use the AutoShapes tool on the Drawing toolbar to quickly draw more complex shapes such as stars and flowchart symbols. (See also "AutoShapes.")
To delete an object, select it and then press Delete.
TIP: To create a perfect square or circle, hold down the Shift key while drawing a rectangle or oval. To add a shadow or 3-D appearance to the object, select the object and then click the Shadow or 3-D button on the Drawing toolbar. Choose the effect you want from the palette.
Excel enables you to easily create exact duplicates of existing objects in your worksheet. You also can move objects to a different position in the worksheet.
Although you can use ready-made AutoShapes to save time when drawing objects, you sometimes may need to manually create an unusually shaped object. The Lines option on the AutoShapes button enables you to create these freehand drawings: curves, freeform polygons, and scribbles. (See "Drawing an Object" and "AutoShapes" before you complete this task.)
When drawing objects, you may find that you want to format or edit many existing objects at once. Instead of having to select each object and format it individually, you can group the objects so they all act as if they are part of the same object. When you group objects, their individual handles disappear and the entire group is surrounded by sizing handles.
To ungroup a set of grouped objects, select the group. Then choose the Draw button on the Drawing toolbar and choose Ungroup from the pop-up menu.
As you create a drawing, you sometimes add objects on top of one another in stacked layers. If you need to adjust the order of these objects, you can use the Order options available from the Draw button on the Drawing toolbar. You may choose to move the bottom object to the top, for example, to adjust its order in the stack. To get the arrangement you want, you may need to rearrange several objects in a specific order.
You can adjust the placement and position of a drawn object by using the Rotate or Flip option on the Draw button of the Drawing toolbar. You can rotate the object left or right, 90 degrees at a time. You can also flip the object horizontally or vertically to reverse the position of the object. This feature is useful when you want a mirror image of an object.
TIP: Click the Free Rotate button on the Drawing toolbar if you need more flexibility when rotating or flipping objects. Drag one of the rotation handles surrounding the object to the position you want. Click the Free Rotate button again to disable the feature.
After you've drawn an object in the worksheet, you may decide to enlarge or reduce the size of an object. You also may want to change the proportions of the object.
TIP: Hold down the Shift key while dragging a corner handle to maintain the proportions of the object.
When you create a chart, Excel uses the default settings for the axis style, tick marks, and scaling. Tick marks are the small lines that appear on an axis, similar to measurement lines on a ruler. You can customize the axis, changing the style of the line used for the axis, the tick marks, the positioning of the tick-mark labels, and the scaling of the axis.
You can enhance the presentation of your data by adding error bars or data labels to a data series. Use error bars to visually display the margin of error in a data series. Data labels are typically used to explain the data points in a chart. You also can change the gap width between the columns in a column chart and make other formatting changes.
You can change fonts and styles in charts just as you change them in worksheets. First, select the elements you want to change, and then make the changes.
TIP: To see additional font options that don't appear on the toolbar, right-click the text element you want to format. Choose Format from the shortcut menu and make your selections from the Font tab; then click OK.
You can format the numbers in a chart just as you format the numbers in a worksheet. For example, you can add dollar signs to the numbers on the value (Y) axis or change the format of numbers used as data labels.
If the numbers in the worksheet you used to create the chart are formatted, the numbers used in the value axis in the chart are formatted the same way. You can override this formatting, however, or add formatting if the numbers in the chart are unformatted.
TIP: To return the formatting to the number formats that appear in the source worksheet, select the Linked to Source option in the Format dialog box.
Excel provides many options and commands that enable you to enhance your chart objects. Chart objects include titles, legends, axes, data series, and so on. You can easily add or change the colors, patterns, and borders of objects in a chart. Excel 97 includes several new patterns, including interesting gradients and textures, that you can use in your charts.
TIP: If you want to change the color or pattern for the chart background, right-click any edge of the chart and choose Format Chart Area from the shortcut menu. Make your selections and then click OK.
For some text objects in charts, such as titles, you can change both the horizontal and vertical alignment, as well as the orientation (or rotation) of the text. For other objects, such as the labels on the axes, you can change only the orientation. You can rotate axis titles or text boxes that contain explanations.
TIP: To quickly select a stacked orientation, reading top to bottom, click the box to the left of the Orientation gauge.
The procedure for importing graphics (or pictures) into your worksheets is similar to the way you insert clip art images. You can insert a picture into your worksheet without opening the program you used to create the picture. After you import a graphic, you can move, resize, or format the graphic. (See also "Clip Art.")
You can add new data to an existing data map at any time. You can insert data in existing categories or add entirely new categories (columnar data) to display in the map. (See "Maps: Creating a Basic Data Map" before you complete this task.)
NOTE: If you want only to insert data in existing categories, select cells in the middle of the current data range; then, from the Insert menu, choose Cells. Select the Shift Cells Down option and click OK. Enter the new region name and data where you inserted the cells and then click the Map Refresh button.
TIP: Double-click the column buttons at the top of the Microsoft Map Control to see the source for the data.
You can add text labels with the size and font you want anywhere on your map. You also can edit existing labels that Excel supplied when you created the map. (See "Maps: Creating a Basic Data Map" before you complete this task.)
TIP: You can move text labels by dragging them anywhere in the map. To format a text label, right-click the text, choose Format Font from the shortcut menu, then make your formatting selections from the Font dialog box. To delete the text label, right-click it and then choose Clear.
You can use the Microsoft Map Control to plot different columns of data and watch the map change. (See "Maps: Creating a Basic Data Map" before you complete this task.)
Excel enables you to easily create a geographical map based on data in your worksheet. The geographic identifiers (such as state abbreviation or country name) should appear in the first column, with data column(s) appearing to the right. Include the headings at the top of the data columns.
You can use maps for many common business applications that involve geographical data. For example, you can create a map that shows how sales and commissions are distributed by region.
The following geographical maps are provided in a standard installation of Excel: Australia, Canada, Europe, Mexico, Southern Africa, UK and ROI, United States (with AK & HI Inset), United States in North America, and World Countries.
If you are unable to access maps, a custom installation of Excel 97 that did not include map information may have been performed on your system to conserve disk space. In this case, you need to run Excel Setup again to install the maps.
The Data Map feature is an Excel add-in written by MapInfo Corporation. Although the maps and data that come with Excel may suit your needs, you also can purchase add-in maps, data, and feature extensions from MapInfo. These maps include census data and features such as roads, cities, and airports. For more information on how to contact MapInfo and purchase these items, activate a data map and choose Help, How to Get More Data.
NOTE: When creating or modifying a data map, Excel displays the Microsoft Map menu and toolbar. These appear only when the map is active.
TIP: To activate a map, double-click inside the map. A thick border appears around an activated map.
NOTE: The data you plan to map must include geographical data, such as country, state, city, or county names; or postal codes. For more information on the types of data you can map and the abbreviations accepted by Excel, see the file named MAPSTATS.XLS. This worksheet also contains sample population sizes and forecasts you can experiment with. To find MAPSTATS.XLS on your computer, click the Start button, then choose Find, Files or Folders; then type the file name and click Find Now.
(See also "Maps: Entering Map Titles.")
You sometimes may use maps to show data at a certain point in time. You also may use maps as decision resources--they present information and plot data so the viewer can analyze the information and use it to support decisions. Excel provides a variety of symbols you can use to customize maps, so the viewer can better understand the differences in the data points.
You can customize each of the map formats to use different symbols, dots, and so forth. For example, you can change the color and symbols used with a graduated symbol format. Or you can change the dot density by specifying how many units each dot represents. (See "Maps: Creating a Basic Data Map" before you complete this task.)
TIP: A quick way to display the customizing options for a map format is to double-click the Map Format button that appears in the work area of the Microsoft Map Control.
You can delete an existing map if you no longer need the map or if you want to create an entirely new map in its place.
NOTE: You cannot delete a map when it is active. If the map is active (an active map has a thick border around it), select a cell in the worksheet to deactivate the map and then proceed with the following steps.
Your data map already includes a main title as soon as you create the map. This title appears in a bordered box at the top of the map. You also can add a subtitle to your map. (See "Maps: Creating a Basic Data Map" before you complete this task.)
You can enhance the appearance of your map titles by changing the font, font styles, and font color used for the titles. (See "Maps: Creating a Basic Data Map" and "Maps: Entering Map Titles" before you complete this task.)
TIP: You can drag the title (or subtitle) to a new location by clicking the title one time and then dragging it by the border. To remove a title or subtitle, select it and then press the Delete key.
The Data Map feature enables you to easily add new data to your map. (See "Maps: Creating a Basic Data Map" before you complete this task.)
When you make changes to worksheet data that your map uses, you need to refresh the map so it reflects these changes. Excel may not automatically update the map as you edit worksheet data. When you need to update the map, the Map Refresh button on the Map toolbar becomes available.
TIP: To change the map refresh from manual to automatic, activate the map and choose Tools, Options. Then choose Automatic and click OK.
Data maps cover a great deal of geographic area, but you may be interested only in a few states or countries. You can magnify maps and reposition them so that they show only the area in which you are interested. (See "Maps: Creating a Basic Data Map" before you complete this task.)
TIP: If you prefer a magnification different from the values in the list, type a magnification. To increase magnification greater than the default, enter a number greater than 100 percent. To decrease magnification, enter a number less than 100 percent.
TROUBLESHOOTING: After zooming in on a data map, the map seems to have disappeared. How do I get it back? You probably zoomed in on a blank area of the map. Click the Display Entire button on the Map toolbar to show the entire map. Then try the zoom procedure again.
To save a chart that is embedded in a worksheet or that appears as a separate sheet in the workbook, you save the workbook that contains the worksheet.
NOTE: When you format and enhance a chart in Excel 97 and save it as an earlier version file, you may lose some of the formatting or enhancements. This is due to incompatibilities between Excel 97 and earlier versions of Excel.
