Create a category chart

Category charts have two key values and one data value. For example, you could map revenues by area and customer.

1. Open a new or existing report in Report Designer.
2. If you are creating a new report, specify the data schema to be used for the report.
3. From the Tool Box view, drag and drop the Category Chart into a container on the report design.
   The Design Window contains a Chart object and its related Item object (shown as a price tag).

4. Select the chart object and enter the values for its properties in the Properties View:
   • Title - caption at the top of the graph
   • Keys Title - caption for the keys
   • Values Title - caption for the values
   • Categories Title - caption for the categories
   • Draw As - the type of chart, for example, Bar or Area. The default is a bar chart.
5. Select the chart's price tag, which represents the item object, and enter the following properties:
   • Key - The data item that summarizes the data. For example, in Figure 1, the key is the category name. The key must be a String.
   • Value - The data item that contains the numbers to be charted. For example, in Figure 1, the value is the unit price. The value must be Numeric.
   • Category Key - Within each key value, the data that you summarize by. For example, in Figure 1, the category key is the sales person's name. The category key must be a String.

   To use a non-string value for Key or Category Key, define a custom string for the key, using the data item in a expression.
