Write more text, such as you all?. The text is centered on the tab stop, indicating that the third tab stop is center aligned.
Press the Tab key again, to come to the fourth and last tab stop.
Write a number such as 1234.567. Notice how the number is aligned at the decimal point. This type of tab stop is useful for numbers.
The text now looks like Figure 8-37.

To allow many more configuration options, use the paragraph format. A quick way to access these configuration options is to double-click on one of the tab stops in the top ruler. You can do this right away with the document you just created in the previous exercise. You will see the configuration dialog, just as at the beginning of this section. You can also get to the configuration options by choosing Paragraph from the Format menu, and then going to the Tabulators page. Play around with the options, which are pretty self-explanatory. You can also add or delete tab stops in this dialog.
If you need permanent tab stops for a specific style, use the Style Manager to edit the tabulators. You can find it in the Format menu as well.
Embedding charts into spreadsheets
KSpread is the spreadsheet component of KOffice. As such, it offers lots of calculation features as well as the ability to create charts to visualize data.
KSpread uses the KChart component for data visualization. KChart can also be used as a standalone charting application.
Now we will take a look at how simple charts can be created inside KSpread.
Assume that you are a company that deals with several products, and you want to see how much profit you can make with each product and compare the results. For this a nice chart is very useful.
Start KSpread with a blank worksheet. The application should look like Figure 8-38.
Entering data into the table is straightforward: simply go to the desired cell with the arrow keys or click on it with the mouse. Now enter data into the table, as shown in Figure 8-39. It does not matter much where you start. In this example, we have chosen cell B4 for the Expense text. After you have entered the data, select the area to create a chart from, as shown in Figure 8-40.
Now click on the Insert Chart toolbar icon, which you can see in Figure 8-40. The mouse cursor changes to a cross, indicating that you now have to select the area where you want to place your chart. Simply draw a rectangle below the table with the left mouse button. After you release the mouse button, a wizard asks you for the chart type you want to insert. Use the default (Bar) and click Finish (Figure 8-41).

The result will look like Figure 8-42. In this chart you see the expense (red on the screen, although it does not appear in color in the printed book), the income (green), and the profit (blue) for each product. If you would like the percentage shown for each of the products, simply double-click on the chart.

Note how the toolbars and the menu change. This is a good example of the tight integration in KOffice, which allows it to use components inside components very flexibly. The menu and the toolbar shown here are the ones that are relevant for the KChart component.
Now right-click on the chart and choose Configure Chart. This brings up a configuration dialog, where you should choose the Chart Subtype configuration page (Figure 8-43). On this page, you can select various subtypes of the current chart type. For this example, select Percent and click OK. The final result will be the nice chart in Figure 8-44. Every
