Microsoft Charts

Historical PPJ desktop distributions integrated the Windows Forms Chart control. Its namespace is System.Windows.Forms.DataVisualization.Charting, and its assembly is System.Windows.Forms.DataVisualization.dll.

Using the Chart Control

For a compatible .NET Framework desktop project, reference the chart assembly and add its Chart control through Visual Studio's toolbox. Confirm availability for the actual target framework rather than assuming an older PPJ installer supplies it for every .NET version. See the Microsoft Chart reference.

Replacing Legacy Graphs

Adding a chart control does not automatically convert unsupported QuickGraph classes. Map the source chart's series, axes, labels, null handling, and selection behavior explicitly. Compare representative output, including negative and missing values. For PPJ Web, select a chart integration supported by the Wisej.NET target rather than using a WinForms control in server code.
