ChartPreview

[Gerben]

Hi,

I upgraded from TeeChartProv5 to v6. The only compile error in my old v5 code so far is with ChartPreview.

I like to run the following code:

uses TeeEdiGene;

With Chart1 do
begin
PrintProportional:=False;
PrintMargins:=Rect(5,5,5,5);
PrintResolution:=-50;
PrintOrientation(poLandscape);
end;
ChartPreview(Main_form,Chart1);

My questions:
1) The uses clause was TeePrevi, and still is according to the tutorial. But then ChartPreview is unknown.
2) PrintOrientation(poLandscape); is also copy/pasted from the tutorial, but poLandscape is unknown. I actually want to use poPortrait. TeeProcs is in my uses list. How to solve this ?

Thanks for your help !

Hi.

The uses clause was TeePrevi

ChartPreview routine is declared and implemented in TeeEdiGene unit. The following code, tested with Delphi 6 and TeeChart 6.01, works just fine:

Code: Select all

Uses TeeEdiGene, Printers;

procedure TForm1.Button1Click(Sender: TObject);
begin
  With Chart1 do
  begin
    PrintProportional:=False;
    PrintMargins:=Rect(5,5,5,5);
    PrintResolution:=-50;
    PrintOrientation(poLandscape);
  end;
  ChartPreview(self,Chart1);
end;

2) PrintOrientation(poLandscape);

To solve this problem, add the Printers unit to the Uses section.

Hi Marjan,

Thanks for the answer, I checked it in Delphi-5 and it worked fine. However it did not completely satisfie my wish.

I have created a chart that definitely has to be printed in portrait mode. Is it possible to bring up ChartPreview with the portrait checkbox checked. Until now landscape is always checked.

I am using Delphi-5 with TeeChart Pro v6.01.

Hi Gerbern,

yes, you can use :

Printer.Orientation := poPortrait;
