ChartDirector 6.2 (.NET Edition)

Data Table (2)




This example demonstrates putting a data table under the x-axis and extend it with additional computed values.

Similar to the previous example Data Table (1), in this example, Axis.makeLabelTable is used to convert the axis labels to a table. The returned CDMLTable object is used to add more content to the table and to configure the appearance of the table.
