Hello all,

is this possible, to set the background of tChart (V8) transparent?

So the Chart will fit in the form with the same appearence.

kind regards
Greeny

Hi Greeny,

Yes, this is possible. I've sent you an example project on how to do that.

thank you Narcís,

I've got it.

kind regards
greeny

Could you send this to me as well?

Thanks Jørgen

Hi Jørgen,

Yes, just sent the project.

Hello Narcis

Could I please also be sent the example of a transparent chart background. thanks

Hi dave555,

Yes, of course. Just sent it to your forums profile e-mail.

Hello Narcis

Thank you for sending me the project. When I run it, I get the result shown in the attached image - definitely not showing a map series with transparent chart background. I am using Delphi 2009 with Vista. Any help would be appreciated.

Thanks,
David

Hi David,

I'm not sure to understand what you mean. I see a map series, and I see the image behind the chart. Could you please explain what you are exactly trying to achieve?

On the other hand, as this new forum allows us to attach files, here is the project for whoever wants it.

Hi Narcis

You are quite right; the demo project does work correctly.

I am saving files in PNG, TIFF and GIF formats. My hope is that in those saved images the chart background could be transparent.

Thanks,
David

Hi David,

I'm afraid that exporting to bitmaps charts with transparency is a known problem already in the wish list to be fixed in further releases.
