Hi there,

I have this code in a userform and get with it a picture in the same size as
the chartobject - to small. I want a much larger (fill the screen as much as
possible). I can easily solve it by changing size of the chartobject before
export to gif, but i dno't want to do that. I want to change the size of the
gif during or after importing it by LoadPicture.

How?

Help = Forever happy

/Regards

Dim ChartNum As Integer

Private Sub UserForm_Initialize()
Debug.Print "frmPPT initilize "
ChartNum = 1
UpdateChart
End Sub

Private Sub UpdateChart()
Set CurrentChart = Blad102.ChartObjects(ChartNum).Chart

' Save chart as GIF
Fname = ThisWorkbook.Path & Application.PathSeparator & "temp.GIF"
CurrentChart.Export Filename:=Fname, FilterName:="GIF"

' Show the chart
Image1.Picture = LoadPicture(Fname)

End Sub
 
Hi Marie -

After this line, resize the Plot Area:

Set CurrentChart = Blad102.ChartObjects(ChartNum).Chart

like this:

With CurrentChart.PlotArea
.Left = 0
.Top = 0
.Width = CurrentChart.ChartArea.Width
.Height = CurrentChart.ChartArea.Height
End With

You may need to adjust slightly, to allow room for the legend, chart title, or axis
titles.

Hi,

I'm awfully sorry, I should have been better explaining my question. It is
more of a userform question than a chart question - maybe. The code i showed
is lokated in the userform code and the userform is a kind of "chart
viewer" to show charts in the userform as picture. I have some buttons in
the userform etc to move between the charts, but didn't mess my question
with that.

The other option I'm thinking of is using a empty chart fullsize chartarea
or a worksheet with a chartobject filling the whole / most of the cells in
the view.

Please Jon, or any other - feel free to give answers to any of the choices
above., as long as it is a code proven to work well...

Kind regards
 
Thanks, i'll look into that.

Regards

Hi Marie -

Gotcha. You need to use a different technique to put the chart onto the
userform. Stephen Bullen shows how to do this by copying the chart as a
picture (not bitmap) and pasting the clipboard contents into the
userform's image control:

Have you tried adjusting the userform control's PictureSizeMode
property? There are three possibilities and the value
fmPictureSizeModeZoom (or maybe fmPictureSizeModeStretch) should do the
job.

Yes, but strech make an awful mess of the chart, even as narrow you try to
get ratio fixed.
Mode does the job, but I find the GIF become lousy quality as well. If you
save the chart in the same size as you later want in GIF, the quality will
be fine.

If I try to copy and paste a chart first and enlarger the new chart and then
delete it make good pictures, but I find Excel to slow to copy paste a
chartobject, even if you of course use screenupdating = false.

/Regards
