Bar Graphs

Bar graphs can be used for:

Comparing independent data sets
Money distribution by time
Production against time

Bar graphs are the most common graph type, and are useful for a wide variety of data. Bar graphs group data together according to categories, displaying one bar for each data item in that category. Each bar is color-coded according to the data series that it represents. Example 13.1 shows how a Bar graph works.

Bar graphs are in the Standard Data Class (see Chapter 12 for details). To create a Bar graph with PopChart XML, create a Graph element and set its Type attribute to Bar, as shown in the example below.
