Data gaps in Waveform Chart

[Dave Wright]

I have a vi designed to show several channels of acquire data on individual charts.  When the vi is running, the data does not fill the chart completeley (there is a variable width gap on the right), and it occasional has a data gap slide down the chart.  I have read other suggestions for similar problems but cannot resolve this issue.  It makes the software look unprofessional and I would love to have it fixed.

Hi Dave,

I'm not sure I completely understand the nature of the gaps that you describe.  Could you attach some screen shots of what you see on the waveform chart?  Also, are you noticing any gaps in data in the file that you save to, or are the gaps only apparent on the chart. 

You may want to try placing the Save to Measurement express VI outside of the While Loop.  The VI will open/configure and close the file every time the loop is run.  If for some reason you need to save the data to file as the program is running, you will want to use the lower level VIs to control when the file is opened and closed. 

What version of LabVIEW are you using?  Also, could you attach the SetCursors subVI (it was not included in your last attachment)?
