Remarks

This container class creates graphs at the record level, unlike the AutoGraph class, which creates graphs from an entire Visual FoxPro cursor. The class also includes a set of buttons to navigate between records and dynamically refresh the chart.

To use, drop the class on a project or form or, from the Component Gallery Item Shortcut Menu, select Add to Project or Add to Form. When you add the class to a form in a data environment, Visual FoxPro opens a builder so you can specify the nChartType and cLblField values for the graph data points and axis labels. When you drop the class on a project, you can choose between adding the class or creating a subclass.
