Hi,
I recently bought the activex teechart because I needed it to be transparent but I can not manage to make it so.
Does this version solves this?
Can you help me?
Thanks.

Hi Alberto,
Which specific chart element do you need to be transparent?
Thanks in advance.

Hello Narcís,
I need line (and fast line) panel (and rest of the graph except axis, numbers, etc. and lines) to be transparent.
Thanks in advance.
Best Regards,
Alberto

Hi Alberto,
In that case you should do something as in the example Yeray posted
here. It's a Delphi example but the same applies to TeeChart ActiveX. Bear in mind that TeeChart Pro ActiveX is a COM wrapper of TeeChart Pro VCL. Example sources:
Code: Select all
unit UTranspChart;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ExtCtrls, TeeProcs, TeEngine, Chart, jpeg, TeeSurfa,
TeeMapSeries, Series, ImaPoint, TeCanvas, TeeGDIPlus;
type
TForm1 = class(TForm)
Image1: TImage;
Chart1: TChart;
Series1: TFastLineSeries;
procedure FormCreate(Sender: TObject);
procedure Chart1BeforeDrawChart(Sender: TObject);
private
{ Private declarations }
Back : TBitmap;
public
{ Public declarations }
end;
var
Form1 : TForm1;
implementation
{$R *.dfm}
procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1.Color:=clNone;
Chart1.Walls.Back.Visible:=False;
Series1.FillSampleValues;
end;
procedure TForm1.Chart1BeforeDrawChart(Sender: TObject);
begin
if not Assigned(Back) then
begin
Back:=TBitmap.Create;
Back.Width:=Chart1.Width;
Back.Height:=Chart1.Height;
Back.Canvas.CopyRect(Chart1.ClientRect,Canvas,Chart1.BoundsRect);
end;
if Chart1.Color=clNone then
Chart1.Canvas.Draw(0,0,Back);
end;
end.

Hi Narcís,
Thanks very much for your help.
Nevertheless, I program in VB 2010 and sorry for been so nuisance but can you tell me how to do that in this language.
I can not access to components as easy as in Delphi probably can be done.
Thanks in advance and best Regards
Alberto

Hello Alberto,
I've been trying to translate that Delphi example to VB 2010 but I haven't achieved it.
I'm afraid we haven't found a way to make the container transparent in ActiveX.

Hello Yeray,
I am a bit upset for this, as I bought the activex with the expectation to get these graphics transparent.
I would like to know if I can get the activex source so that I can change it myself.
Regards,
Alberto

Hello Alberto,
After some more investigation I found the equivalent VB 2010 project of the Delphi project I pointed you at. It can be downloaded here:
http://steema.com/files/public/Transpar ... XChart.zip
The key was finding the exact properties that match the VCL/ActiveX ones and also some type conversions from .NET to ActiveX. One interesting article on the subject is this:
