saveGraphImage woes

smikes

Hi, I'm trying to create several plots in succession and save them to files automatically. Running into trouble with saveGraphImage()

win0 = awvCreatePlotWindow()
awvPlotWaveform(win0 vtuneL ?expr cornerL)
awvDisplaySubwindowTitle(win0 "vtune")
awvSetLegendWidth(win0 400)
saveGraphImage(?fileName "~/Images/vtune.png" ?width 1280 ?height 720)

 

If I run this, the file is created but the waveforms are "undersampled", as though only 1 out of every 100 points were actually used to draw the line. The graph that pops up in ViVa looks nice and smooth, and if I run the exact same saveGraphImage() command again from the CIW, it produces a file with smooth waveforms. 

Now, I tried placing the saveGraphImage() call into a hiRegTimer, and this fixed the issue for a single case. When I add another plot though, only the last one gets saved "smoothly", the first becomes coarse again no matter what I tried.

Running ICADVM 18.1-64b.500.11

Thanks in advance!

    I just found a report of a similar sounding bug, CCR 2209855. This has been fixed in IC6.1.8 ISR15 (due 20th November). I would suggest contacting customer support - maybe we can provide you with an early access to this or engineering hotfix to ensure that it is really solved? It's too late to get it into ISR14 as that is due at the end of this week.

    Regards,

    Andrew.

    Hi Andrew

    I am also facing the same issue, and it's even worse that no signal is loaded. Only the signal name and strips.

    I have tried the workaround from CDN support by placing sleep() between the awvLoadWindow and saveGraphImage, but this does not help.

    And I have also tried hiRegTimer, and it does not complete solve the issue. Only one or two images are saved properly.

    Where can I find the hotfix? I do not find it in the CDN support.

    By the way, we cannot easily move to the latest Virtuoso due to project setup constrains. Thus I hope there is a solution/workaround for the early versions.

    Best Regards
