Namespace: DevExpress.XtraCharts.Heatmap

NuGet Package: DevExpress.Win.Charts

Declaration

A Stream object to which the created document is exported.

Optional Parameters

Name Type Default Description

An object that specifies the HTML export options to be applied when a diagram is exported.

Remarks

To show the standard Print dialog, use the HeatmapControl.Print method. This dialog allows users to print the diagram, select the printer, specify the range of pages to print, the number of copies, and so on.

To display the DevExpress Print Preview, use one of the following methods:

Method Description
HeatmapDiagramControl.ShowPrintPreview Creates a print document and displays the Print Preview dialog.
HeatmapDiagramControl.ShowRibbonPrintPreview Creates a print document and displays the Print Preview with the Ribbon toolbar.

To export the diagram, use one of the ExportTo~ methods (for example, call the HeatmapControl.ExportToPdf method to export the diagram to a PDF file).

Important

The diagram can be previewed, printed or exported to other formats only if the Printing library is available (except when you export to raster and vector images). Ensure you add a reference to the DevExpress.XtraPrinting.v24.1 assembly.

Note that the DevExpress.Pdf.Core library should be available to export the heatmap to PDF.
