July 29, 2009
1. Click the Data tab.
2. Using the downward pointing arrow on the right side of the Dataset name box atop the Data tab, display and select the ProductData dataset, as shown in Illustration 17.
3. Click the Add... button to the right of the Values list box, found immediately underneath the Dataset name selector we populated above.
The values in a Value series determine the size of the slice in the Doughnut. Multiple Value series appear as separate slices. If we have multiple Category or Series groups, the group labels are displayed in the chart legend.
The Edit Chart Value dialog appears, defaulted to the Values tab.
4. Type the following into the Series label box, atop the Values tab:
5. Click the function (fx) button to the right of the Value box, depicted within a circle in Illustration 18.
The Expression Editor opens.
6. Click the Fields (ProductData) option in the bottom left corner pane of the Expression Editor.
The field values of the ProductData dataset appear within the pane in the bottom right corner of the Expression Editor.
7. Double-click Internet_Sales_Amount to place this selection into the main pane atop the Expression Editor.
The Expression Editor appears, with our input, as shown in Illustration 19.
8. Click OK to accept our input and to dismiss the Expression Editor.
We are returned to the Edit Chart Value dialog, which appears with our input as depicted in Illustration 20.
9. Click the Appearance tab on the Edit Chart Value dialog.
10. Click the Series Style... button in the lower left corner of the Appearance tab.
The dual tabbed Style Properties dialog appears again, just as it did for the Chart Area Style... and Plot Area Style... buttons we examined earlier. We see the same Border and Line and Fill tabs, which we will leave at default at this point.
11. Click OK to dismiss the Style Properties dialog, and to return to the Appearance tab of the Edit Chart Value dialog.
12. Click the Point Labels tab on the Edit Chart Value dialog.
13. Click the check box to the immediate left of Show point labels atop the Point Labels tab.
14. Click the downward pointing arrow to the right of the Data label box to display data selection options.
15. Select =Fields!Internet_Sales_Amount.Value from the options, as shown in Illustration 21.
16. Within the Format code box (just underneath the Data label selector) type the following character pattern:
17. Uncheck the Auto checkbox to the right of the Format code box.
This will result in the point labels being displayed outside the Doughnut, at an angle to a connecting line, making the chart more compact and, in this case, making the labels themselves somewhat easier to read.
18. Click the Label Style ... button immediately underneath the Angle setting.
The Style Properties dialog box appears.
19. Make the settings, listed in Table 2 below, within the Style Properties dialog box:
Table 2: Style Properties Dialog
The Style Properties dialog appears, with our settings, as depicted in Illustration 22.
20. Click OK to accept settings.
The Style Properties box closes. We return to the Edit Chart Value dialog box, which now appears as shown in Illustration 23.
21. Click the Action tab of the Edit Chart Value dialog.
Here we can define Hyperlink actions, including Jump to report, Jump to bookmark, or Jump to URL. We will not be working with a drillthrough scenario in this practice session, and so will leave undisturbed the default setting of None, as depicted in Illustration 24.
22. Click the Data Output tab of the Edit Chart Value dialog.
The Data Output tab affords us a means of defining XML data output options for the values in the chart. We will not leverage these capabilities within this introduction to Simple Doughnut charts, and will therefore leave the settings of the Data Output tab at their defaults, as shown in Illustration 25.
23. Click the OK button at the bottom of the Edit Chart Value dialog, to dismiss the dialog with our settings.
We are returned to the Data tab of the Chart Properties dialog. Next we will work with the Category groups area of the tab, just under the Values area. Categories are displayed as individual slices in the Doughnut. Each Category is displayed in the chart legend, when the legend is selected for use.
24. Click the Add... button to the right of the Category groups list box, found immediately underneath the Values list box with which we worked above.
The Grouping and Sorting Properties dialog appears, defaulted to the General tab.
25. Type (or cut and paste) the following into the Name box, atop the General tab:
26. Click the top row of the Expression box within the Group on section that appears just underneath the Name box, to enable the selector button (the downward-pointing arrow) on the right side of the box.
27. Select =Fields!Sales_Reason.Value from the options that appear, as depicted in Illustration 26.
As we have no input for the Filters or Data Output tabs (which resemble their counterparts in other areas of the Report Designer, as we have, and shall, see), within the context of this newly added group, and as we intend to leave the Sorting at the settings naturally found within the cube structure (the Sales Reasons will sort, where appropriate, in alphabetical order), we will accept our input at this stage.
