Graph By Record Foundation Class
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.

Remarks
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.
