The WinForms Rich Text Editor uses WinForms Spreadsheet Charts to render, import, and export documents that contain charts. Follow the steps below to enable spreadsheet charts in the Rich Text Editor:

1. Add references to the following assemblies:

   • DevExpress.Spreadsheet.v24.1.Core.dll
   • DevExpress.XtraSpreadsheet.v24.1.dll
   • DevExpress.Charts.v24.1.Core.dll
   • DevExpress.XtraCharts.v24.1.dll
   • DevExpress.DataVisualization.v24.1.Core.dll
   • DevExpress.TreeMap.v24.1.Core.dll
   • DevExpress.XtraTreeMap.v24.1.dll

2. Call the ActivateWinFormsCharts method before the control is initialized:

   C#

   using DevExpress.Office.Services;
   using DevExpress.XtraSpreadsheet.Services;
   // ...
   
   public Form1()
   {
       OfficeCharts.Instance.ActivateWinFormsCharts();
       InitializeComponent();
   }
   

   VB.NET

   Imports DevExpress.Office.Services
   Imports DevExpress.XtraSpreadsheet.Services
   ' ...
   
   Public Class Form1
       Public Sub New()
           OfficeCharts.Instance.ActivateWinFormsCharts()
           InitializeComponent()
       End Sub
   End Class
   

Charts are stored in the SubDocument.Shapes collection. Use the ShapeCollection.InsertChart method to add a chart to a document.
