Description
See enclosed picture, obtained from a simple MSL ramp.
On my hi-res screen I chose 4 pixel width for plot curves.
The last horizontal segment is two (instead of four) pixel wide.
Just a minor glitch, but worth mentioning, I think.

I found a case that makes me change priority of this ticket. Consider the enclosed refSpeed.mo refSpeed.png, refSpeed.svg.
The png is VERY bad!

Has anyone seen the plots in this ticket? I see it is still catalogued as new defect.
Especially refSpeed.png and refSpeed.svg are worth looking at.

@ceraolo, I just opened #5515, which addresses a significant usability issue when dealing with PWM signals. I guess the solution proposed there would also fix this issue, what do you think?
comment:7 by , 5 years ago
Yes, adding some top and bottom margin should solve also this ticket's issue.
In addition, this ticket shows that PNG's are much worse than SVG's, not only because of the extrema values but also for the quality of text.
Once #5515 is solved maybe this #4937 can be closed and an additional one could be open to address PNG quality. It should be easy to improve PNG's since we have the corresponding SVG which is ok.
BTW, have you tried the quality of SVGs obtained from you PWM signals?

Those PNGs are just raw screen captures to show what I see on screen.

Replying to casella:

Not quite so.
Look at Comparison.pdf.

I see, sorry, I messed up with another ticket
@adeas31, why is the png export of worst quality than the rendering on the screen?

The curves cutting issue is solved in #5515.
The PNG export quality is improved in 28e53ad/OpenModelica.

I found another very telling case.
Compare the screenshot (PlotCutShot.png) with the svg created from the plot: plotCut.svg (the latter is correct, and very nice).
