distorted fat line in XY graph

[Wolfgang]

Hello,

sometimes, depending on my data, the call to PlotXY ( ,,,,,,,VAL_FAT_LINE,,,, ); results in somewhat irritating lines; I imagine that it has to do with antialiasing which is enabled for my graph but still I feel that the line could be drawn nicer, see the left Gaussian below:

I can add that if I zoom into the graph the line looks o.k., so I can definitely exclude a problem with the data set.

Hello Wolfgang,

Would you be able to post a project which reproduces this type of graph rendering?  I have been trying to reproduce the issue using PlotXY, but have been thus far unsuccessful.

Thank you,

[Wolfgang]

I hope so... but it will be few days until I find some time...

[Wolfgang]

OK,

I have prepared a demo showing the effect.

Hello Wolfgang,

Thank you for creating that project—I have been able to reproduce the issue as far back as LabWindows/CVI 2009.  I have filed a bug report, 432165, for this issue.  

As a note, I noticed that I could resolve the incorrect rendering by doing one of the following things:

• Disable Anti-aliasing
• Enable Plot Legends
• Disable Y-Axis Labels
• Resize the Graph

Please let me know if you find more ways to get around this issue.  We appreciate your feedback!

Warm Regards,

[Wolfgang]

Hi and thanks for confirmation!

Also thanks for the note of how to resolve it, (but I prefer to stick to my current settings, hoping that the fix won't be complicated )

unfortunately this issue has not been fixed so far
