Export a chart in a PDF file

[ACDTOURS]

Hello,

I get the following output when I try to export to PDF, a graph with the gradient property enabled

I use a pie chart, and for each part of the pie, a colored square appears.

These squares are not seen during the preview that presents a correct result.

I tried to change the options on the component, but without any success.

I hope someone can help me.

best regards

Hi,

Could you please show us some screenshots and even better, could you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

As an alternative to the exportation to pdf TeeChart integrates, you could try to export your chart as an image and use a virtual pdf printer to get the pdf from it.

Here is the result in the preview



And the result when exporting pdf


It is extremely difficult for me to give you a simple example program.

We are working on a project whose sources are interconnected and therefore difficult fragmentable

I hope these screenshots will help you ...

Hi,

Are you using the latest version v2013.08?
I've made a simple example to try to reproduce it. Just place a Chart and two buttons in a form; and use the following code:

Code: Select all

uses TeePDFCanvas, TeExport;

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.Legend.Visible:=false;

  for i:=0 to 3 do
    with Chart1.AddSeries(TPieSeries) do
    begin
      FillSampleValues;
      Marks.Visible:=false;
    end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  TeeExport(Self, Chart1);
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  TeeSaveToPDFFile(Chart1, 'C:\tmp\test.pdf');
end;

Then you have three ways to create a pdf:
- Click button1 to show the Export dialog. Select "as PDF" Format in the "Export\Picture" tab. Click the "Preview" button.
- Click button1 to show the Export dialog. Select "as PDF" Format in the "Export\Picture" tab. Click the "Save" button. Give a name to create the pdf file.
- Click button2.

I get a correct pdf following any of the three ways:

At first, thank you for your reply.

I tried the code you provide for me and ... it works.

However, it seems to persist a little problem.

I changed the options TChart (adding a ChartEditor and throwing on the double click of TChart).

I then changed the Gradient property to make it visible

The result of the component is as expected



The preview bmp and its export is correct.



The preview metafile and its export is also correct.



But when exporting to PDF format, you lose the concept of gradient.


Do you have any idea?

Hi,

I'm afraid the gradients aren't exported to pdf. This is an enhancement already present in the wish list to be implemented in future releases (TV52016633).

[ACDTOURS]

OK thank you for all your replies.

[ACDTOURS]

One last thing.

Do you have an approximate date for this release ?

[Yeray]

Hi,

No, I can't tell you a date for it to be implemented.
In the meanwhile, have you tried the alternative suggested above, using a virtual printer?

[ACDTOURS]

It will be difficult but we'll see.

Thank you for the time spent helping me.
