Using a hidden chart control to create bitmaps


Recommended Posts

In our application the chart control is not always displayed for all

operations. Such as when Undo/Redo is done, the chart control is not needed

to be displayed. I have found one situation when the chart control is

hidden and i set all the properties up i cannot get the SerLegBox to display

on the bitmap. It only works if the chart control is visible. Is there a

way around this?

If you would like to see a sample app with this let me know.

I tested this and the series legend box appears (even though the size is

incorrectly calculated so we are working on a fix for that). This code was

placed on a button in a default Windows Form app.

Chart chart2 = new Chart();

chart2.Width = 200;

chart2.Height = 200;

chart2.Gallery = Gallery.Lines;

chart2.OpenData(COD.Values,2,3);

chart2.Value[0,0] = 10;

chart2.Value[0,1] = 12;

chart2.Value[0,2] = 6;

chart2.Value[1,0] = 2;

chart2.Value[1,1] = 3;

chart2.Value[1,2] = 8;

chart2.CloseData(COD.Values);

chart2.SerLeg[0] = "A";

chart2.SerLeg[1] = "B";

chart2.SerLegBox = true;

chart2.Export(FileFormat.Bitmap,"D:\\Temp\\Chart.bmp");

Are you doing something different ?

Can you post a small sample that duplicates your issue ?

Ok here is the sample app that demostrates this.

1) Start the app

2) Hide the Chart using the Hide Button

3) Try to turn on the Legend while the chart is hidden (it wont turn on

for me)

4) Then create the bitmap (bitmap is created without the legend) (this is

a problem for opererations such as Undo/Redo where we use the control in a

hidden state to recreate the bitmap)

Also i have noticed that when the legend is displayed we do not get the

DoubleClick event when double clicking on the legend area of the chart.

We have fixed this bug and the fix will be included in our next service

pack.

> Also i have noticed that when the legend is displayed we do not get the

In our current service pack we are generating MouseDown events for the

dataeditor and legend box, our next service pack will also generate MouseUp

and DoubleClick events for these objects.
