Trong khóa này, ta chọn Visual Studio Default | Chapter 3 When you click OK to exit the Chart Expert your Chart will be added to your Report Header. When you see the report in the designer a pie chart should now be displayed in the Report Header. This isn t an accurate drawing of your graph. In fact it is nothing like your graph it is just a placeholder to show where in the report the graph will be positioned. If you preview the graph in a Windows form it will look something like Figure 3-34. Another option to increase readability would be to make the chart larger. The chart object inserted into your report is just like any other object in that it can be resized to fit your needs you could even resize the graph to take up the entire first page if that suits the needs of the report. If you have a graph or chart inserted into your report you can control the content by right-clicking directly on top of the chart and selecting an option from the menu. The Chart Expert can be used to alter the graph in the way that we have described so far in this section. You may have noticed that the Chart Expert includes an option on the first tab labeled Automatically set chart options. If you uncheck this box two more tabs will appear allowing you to control other aspects of the report including the formatting for the graph axes and the general settings like color marker size and so on . Under Format Chart are the Template General and Titles options which also allow you to customize the appearance of your chart. The options in all of these menus are context sensitive for example you can perform different types of formatting to a pie chart than you can to a bar chart. These options are all relatively simple so we ll leave it to you to explore the almost endless possibilities. Figure 3-34 92 Designing Reports Unfortunately if you have used the retail version of Crystal Reports before you will probably be wondering what happened to the Chart Analyzer which allows you to open the graph in another tabbed window.
