I am trying to export a JPEG image of a pie chart I have created. If I do not resize the image, it looks great - but if a try to resize the Chart it is unreadable - pie shape changes radically or disappears, etc.

Code I use in Visual FoxPro (VFP):

With thisform.mmTeeChart_Pie.Export.asJPEG
.CompressionQuality = 90
.GrayScale = .F.
.Height = 105
.Width = 120
.SaveToFile("c:\pie.jpg")
ENDWITH

All I want is an image that looks EXACTLY like the bigger version - only smaller (like a thumbnail). Maybe just specify width and be able to use "Keep Aspect Ratio" type command to calculate the height. Is that possible?

Hi Tom,

This is because chart's legend and pie's mark don't let the pie be visible you can do something like this:

Code: Select all

Private Sub Command1_Click()

    TChart1.Legend.Visible = False
    TChart1.Series(0).Marks.Visible = False
    
    With TChart1.Export.asJPEG
        .CompressionQuality = 90
        .GrayScale = False
        .Height = 105
        .Width = 120
        .SaveToFile ("c:\temp\pie.jpg")
    End With
    
    TChart1.Legend.Visible = True
    TChart1.Series(0).Marks.Visible = True
End Sub
