Problem of Printing Axis' Labels and Titles

[DVT]

I have one existing application which was based on V505. After I updated the version to 2013, the printed labels/titles are off the axis to somewhere at the top-left corner and the font size is way smaller; the chart's titles are not lined up either, and the font size is smaller; border lines are drawn at the right and bottom.

Hello,

This looks very similar to this:

Could you please try if disabling GDI+ gives better looking prints?

Hi there,

Thanks for your help. Setting GDI+ to false is a workaround for the font and size of printed axis labels and titles, but the right and bottom lines still appear on the printed sheet (no lines on the screen).

I'm currently using TeeChart2013_0_1_1ActiveX3264, though the file version of TeeChart2013.ocx says "2012.0.0.8". I downloaded the latest version from your website which was TeeChart2013_0_1_4ActiveX3264. However, I got an error message saying "Error while activating license: 1168" while I was trying to do update it by using my license number, which I got only a couple of months ago (last Dec.).

Could you please attach a simple example example project we can run "as-is" to reproduce the problem here?

I see no reason why the license number you use to log into this forum should give an error activating the license. Please contact our Sales Dept. at sales at steema dot com with your licensing details and any activation number the installer may provide.

Thanks in advance.

Hello,

As an update, the issue discussed here may be related to what Pep posted here.

Today I tried your latest version (TeeChart Pro Activex Control v2014, v2014.0.0.2 Released on 20th November 2014). It looked like the issues were still not solved. I used it in an MFC project in Visual Studio 2012 (Win 7).

The attached shows the problems:
1. Axis's name (or title): it was printed at the top-left corner far away from the axis (should at the left-middle close to the axis's labels), if set GDI+ as true.
2. Axis's labels (numbers): they were to close to the plot (overlapped), if set GDI+ as true.
3. Axis's name (or tile): it was to close to the axis's labels and overlapped, if set GDI+ as false.
4. Extra lines: one lien on each of the bottom and the right edge, no matter GDI+ is set as true or false.
5. And the titles were still messed up (see the previous attachment DVT_print_issue.png)
The screen and preview were perfect.

Hello,

I've created a simple application in VB6 with just a Chart and a Commander on the form and this code:

Code: Select all

Private Sub Form_Load()
  TeeCommander1.ChartLink = TChart1.ChartLink
  
  TChart1.Aspect.View3D = False
  TChart1.Legend.Visible = False
  
  TChart1.AddSeries scLine
  TChart1.Series(0).FillSampleValues 100
  
  TChart1.Axis.Left.Title.Caption = "Depth (m)"
  TChart1.Axis.Bottom.Title.Caption = "Offset (m)"
End Sub

I've printed the chart to a pdf virtual printer (PDFCreator) through the "Print" button in the commander.
Then I've opened the editor through the commander and switched from GDI+ to GDI at the "Chart\3D\Render" tab.
Finally, I've closed the editor and printed the chart again with the same tool and the same "Print" button in the commander.

Both charts look correct in the pdf files:

Could you please check if printing to a pdf virtual printer also reproduces the problem for you?

[DVT]

Yes. The problems are still persist.
1. After using the new TeeChart2014 (and 2013), the title on print out are not aligned properly, no matter set GDI+ true or false. It looks the exactly the same on screen as before.
1. On the pdf print out, it is the exactly the same result as on a paper print, the y-axis title is printed at the top-left corner and the font is way smaller and hard to see.
See the attachment.

Good. At least we'll be able to make the necessary tests without wasting paper

Looks like the latest version (2014.0.0.2) fixed most of the problems. However, there is still one issue on print out - one line on each left and bottom. The attached sample project shows that. To build the project, the files in Tee_Files_0 and TeeFiles_1 need to put in the project's Tee_Files folder which is empty in the MFCApplication1.zip file.

The result will be followed due to the limitation to the files attached.

The print out issue: extra lines on right and bottom.

Hello,

You can set the Outer Bevel to none as noted here.
In your case, you can do as follows to save the status of the Outer Bevel and restore it after printing:

Code: Select all

void CMFCApplication1View::OnFilePrint() 
{
	if (m_pChart.GetPrinter().ShowSetupDlg()) {
		int tmp = m_pChart.GetPanel().GetBevelOuter();
		m_pChart.GetPanel().SetBevelOuter(0);
		m_pChart.GetPrinter().PrintChart();
		m_pChart.GetPanel().SetBevelOuter(tmp);
	}
}

[DVT]

Thanks. That works.

I tried printing my chart with setting the GDI+ to TRUE and FALSE. It looks nicer on the print out when setting the GDI+ to FALSE than setting it to TRUE. In what scenario is GDI+ supposed to be set to TRUE?

It's up to you. We find GDI+ draws smoother lines and texts but some customers find it blurry.
In general we'd probably use GDI+ to create visually attractive charts but GDI if the performance is in compromise. Also note OpenGL, that takes a bit to initialize but it's both pretty and fast after it.
