95. Insert a Chart into a Presentation
94 Change a Presentation's Background 96 Insert Graphics into a Presentation A chart can summarize your presentation, and audiences often glean information from charts that they might not otherwise get from long lists of data or from you listing scores of numbers for them. So often you'll want to use charts in your presentations to make your data more available to your audience.Impress (as does Writer) includes its own Calc-like charting capability. Impress accomplishes this by supporting the use of a mini-version of Calc right inside Impress. In other words, when you want to place a chart on an Impress slide, you can build the chart from within Impress, entering data into a spreadsheet as though Calc were inside Impress, ready to build your charts.68 Add a Chart to a Spreadsheet , although a Calc-based lesson, describes charts and terminology related to them. If you are unfamiliar with OpenOffice.org charts, take a few minutes to review this task.[View full size image]

1. | Request a Chart You can insert a chart in any slide. If the slide contains a chart placeholder (a small icon of a chart), double-click the placeholder to add the chart. If the slide doesn't contain a placeholder, choose Chart from the Insert menu. Impress places a sample chart directly in the center of your slide and closes the Slide and Task panes (if they are open) to give you more room to work with the chart. You now must position the chart where you want it and change the data values used in the chart to match the data you want to portray in the presentation. In addition, you can change the chart type as well as all its labels.68 Add a Chart to a Spreadsheet describes each chart type and the best use for each one. |
4. | Modify the Data in Spreadsheet Form When you select Chart Data from the right-click menu, a small spreadsheet appears in the center of your slide. This is a Calc-like spreadsheet add-in program. Although all of Calc's features aren't represented in Impress's spreadsheet, you can easily enter the data needed to create your chart in the rows and columns there.Replace the sample row and column labels with your own data's label information. Replace the data inside the spreadsheet's body with your own data. You can add or delete rows or columns, simply by selecting a row or column that precedes the one you want to add or by selecting a row or column to delete. You may sort by rows or columns, as you might do if you wanted data to appear alphabetically in the chart.OLE object . You must tell Impress that you want to edit that object when you want to make additional changes, such as changing the title or legend rather than simply moving or resizing it. |
KEY TERMOLE object
Abbreviation for Object Linking and Embedding . This term refers to an object that can be placed inside documents of different types, such as a Writer word processing document and an Impress presentation. You can place charts in Impress and Calc because OpenOffice.org converts the charts to OLE objects that both programs accept.Once you've entered your specific data into the chart, the AutoFormat dialog box is the simplest place to update all the chart's details, such as titles and legends. After double-clicking the chart, select AutoFormat from the right-click menu to modify the other chart features, including changing the chart's type, such as from a bar chart to a pie chart.
