Labview: how to set the time range in a Waveform Chart

I have a Waveform Chart in Labview. I know that I can change its range using the "Plot History Length" property. The problem is that I don't add the points to the plot regularly, so I can't compute the number of point I want to be displayed.

Is there a way to inform Labview that I want only the points from last, let's say, 20 minutes to be displayed?

I want to display an absolute time, so setting range to 20 min won't help.

Try to use X-Y graph instead of Waveform chart, and assign your time data to the X axis.

OR: Use waveform chart, select absolute time, modify min.range and max.range properties of Time axis to show up the range Current time -20 to Current time enter image description here

Use the right tool for the job, being the Waveform Graph instead of the Waveform Chart. Takes a 2D array of points so you can have arbitrary X axis spacing.
