Wrong chart title position on print

[hansw]

Hello,

when the chart title position is left justified or right justified then the position on print is wrong. If the position is left justified then the chart title text is not readable (truncated).
For example: Use the following code

Code: Select all

  Chart1->Title->Alignment = taLeftJustify;
  Chart1->Title->TextAlignment = taLeftJustify;
  Chart1->Title->Text->Clear();
  Chart1->Title->Text->Add(L"Chart Title Line 1");
  Chart1->Title->Text->Add(L"Chart Title Line 2");

to have two chart title lines which are left justified. Then use the ChartPreviewer component to print the chart => only small parts of the chart title is printed.

The attached project is for C++Builder 10.1 Berlin using TeeChart Pro 2016.18.

Is there a workaround for this bug?

With best regards

Hello Hans,

The problem is caused so the Text aren't drawn in the print area, therefore I would like suggest you modify the print area margins, so the titles can be drawn without problems.
To do this, you should add the lines below in the Print button:

Code: Select all

void __fastcall TForm1::Button1Click(TObject *Sender)
{

	Chart1->PrintProportional =false;
	Chart1->PrintMargins =Rect(2, 5, 2, 5);
	ChartPreviewer1->Execute();
}

Also, I have attached the project you sent me, with the modified code.

Hoping this helps you
Thanks in advance,

Hello Sandra,

thank you for the quick reply. Your solution works also for the real application. However, I would see the solution as workaround because in the print preview the title is always displayed within the margins. And the chart title left position is in line with the left axis title. So there is no reason for the chart title text to be truncated in the print output.

Hello Hans,

Seems the problem is caused for the print Orientation. We're investigating where is the problem. Meanwhile, I would suggest you modify the print area margins or enable the Smoothed options before print.

Thanks in advance

Hello Sandra,

I will stay with the modification of the print area margins, the print output looks "pixelated" if the "Smoothed" option is turned on.

Good afternoon Hans,


Finally, after doing some test, I have decided add the problem you are experiencing in the TeeChartVCL bugzilla tracker to fix the problem to upcoming versions. Here's the problem: http://bugs.teechart.net/show_bug.cgi?id=1595
Feel free to add your mail to the CC list of the other tickets to be automatically notified when they'll be updated.

Thanks in advance,

Hi Sandra,
is there meanwhile a solution available ?
I have the same problem with printing my charts:
The ChartPreview is oK, but on the printer the title text will be truncated in case the alignment of the title is taLeftJustify.
Even if I change it to taRightJustify the position of the text seems not to be exactly on the right side.

Kind regards

Hello Juergen,

Have you tried the workaround Sandra suggested above?

[JRadke]

Hello Yeray,

sorry for my late answer.
Yes, the workaround solves the problem.
Accidentally I've tried it with

Code: Select all

Rect(5, 5, 5, 5);

instead of

Code: Select all

Rect(2, 5, 2, 5);

That was the reason it seemed not working.
Thank you.
