About the point style of ImagePointSeries?

[wwp3321]

I have changed the type of the point style to "Square" at the style combobox ,then run the BCB6.0,but the points painted on the form
are not "Square",just the default blue points.

I have tried all the types in the combobox ,but nothing to get changes,
just the default blue points.

Hi wwp3321,

You need to set Pointer.Style and load pointer image later, for example:

Code: Select all

        Series1->FillSampleValues();
        Series1->Pointer->Style=psRectangle;
        Series1->ImagePoint->LoadFromFile("C:\\temp\\polargrid.bmp");

I didn't want to set a custom picture as point style,just to select the styles
that tchart offered in the style combobox.

I have added points to series liking following.

Code: Select all

Chart1->Series[0]->FillSampleValues(100);
Series1->Pointer->Style=psRectangle;
//Series1->Pointer->Style=psDiamond;

But the points painted are still blue default points .

Hi wwp3321,

Yes, I saw the pictures.

In that case you could use a standard points series where you can set the pointer style and also set a specific image for it. Images can be loaded to series' pattern.
