MrDeathStar Posted May 26, 2015 Share Posted May 26, 2015 I found a strange graph problem...if I set a graph component's Bottom Axis 'Time Width' to 15 seconds, then graphing will stop painting during trending. I have tried versions 5.87c, 5.91/2203, 5.91/2213 and express on two different machines. I discovered this issue when using the streaming mode / LabJack, but found I could duplicate it without hardware. Creating a 2D graph of a Test channel (timing 1.0) will show the problem after a few repaints (typically less than 20 seconds). I have not found any correlation to Page Refresh (tried .25, .4, .5, 1, and 2 seconds). Is this a known issue? Are there other poor choices for Time Width (i.e. factors of 15)? I was implementing a user control that allows dynamic adjustment to view trace details, but may need to reconsider. Link to comment Share on other sites More sharing options...
AzeoTech Posted May 27, 2015 Share Posted May 27, 2015 My guess is there is something else going wrong, such as a frozen X axis. Can you please provide a sample that shows this behavior? Link to comment Share on other sites More sharing options...
MrDeathStar Posted May 27, 2015 Author Share Posted May 27, 2015 I had to make the sample quickly before it stops...but I attached the file. Give it from 10 to 30 seconds to run and the graph stops...DAQFactory stays in memory if closed. Simple steps to reproduce sample: (1) make a test channel with 1 sec timing, (2) Insert a 2D graph for the test channel, (3) set the Bottom Axis time width to 15, (4) watch the channel graph and stop in about 30 seconds or less.

MrDeathStar Posted May 28, 2015 Author Share Posted May 28, 2015 BTW: Testing with Express on various lab laptops took a bit little longer...a little over 1 minute...but all resulted in the graph freezing unrecoverably. Link to comment Share on other sites More sharing options...
AzeoTech Posted May 28, 2015 Share Posted May 28, 2015 Do you find any other numbers fail? I see the 15 seconds, but didn't see any others that failed. Link to comment Share on other sites More sharing options...
AzeoTech Posted May 28, 2015 Share Posted May 28, 2015 OK, we've resolved the issue. You can try the patch at the same place you downloaded before, or email us for the link if you don't have it. Link to comment Share on other sites More sharing options...
