Chart Printing (Chart Controls)
In the Chart Control for Windows Forms, you can print the chart picture. To do this, use the Chart control's Printing property. This object prints all the Chart control's elements at the current data view, except for scroll bars.
You can invoke the Print dialog box or print in the background. In the Printing object, the PrintDocument property allows you to set printing properties, such as page margins.
Custom Printing
To print the chart picture in a document that contains other document elements, invoke the PrintPaint method inside a PrintPageEventHandler. You must pass to the PrintPaint method the Graphics property from the PrintPageEventArgs object, along with a Rectangle object that defines the position of the chart picture in the document.
The following code demonstrates printing a document with a line of text, then the chart picture, then another line of text.
' Create new PrintDocument
Dim pd As New System.Drawing.Printing.PrintDocument()
' Add the event handler, and then print
AddHandler pd.PrintPage, AddressOf pd_PrintPage
' Print the document
pd.Print()
...
Private Sub pd_PrintPage(ByVal sender As Object, ByVal ev As PrintPageEventArgs)
' Create and initialize print font
Dim printFont As New System.Drawing.Font("Arial", 10)
' Create Rectangle structure, used to set the position of the chart
Dim myRec As New System.Drawing.Rectangle(10, 30, 150, 150)
' Draw a line of text, followed by the chart, and then another line of text
ev.Graphics.DrawString("Line before chart", printFont, Brushes.Black, 10, 10)
chart1.Printing.PrintPaint (ev.Graphics, myRec)
ev.Graphics.DrawString("Line after chart", printFont, Brushes.Black, 10, 200)
End Sub
// Create new PrintDocument
System.Drawing.Printing.PrintDocument pd = new System.Drawing.Printing.PrintDocument();
// Add a PrintPageEventHandler for the document
pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
// Print the document
pd.Print();
...
private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
// Create and initialize print font
System.Drawing.Font printFont = new System.Drawing.Font("Arial", 10);
// Create Rectangle structure, used to set the position of the chart Rectangle
myRec = new System.Drawing.Rectangle(10, 30, 150, 150);
// Draw a line of text, followed by the chart, and then another line of text
ev.Graphics.DrawString("Line before chart", printFont, Brushes.Black, 10, 10);
chart1.Printing.PrintPaint (ev.Graphics, myRec);
ev.Graphics.DrawString("Line after chart", printFont, Brushes.Black, 10, 200);
