fixed Y axis range with Auto minimum or Maximum in waveform chart

Hi,

 

     I am trying to wire a code for waveform chart. I need Y axis to have a fixed range, while minimum or maximum value following plot or auto scale. Is it possible? Also I need to show difference in points (y-axis value) in chart for a constant period of time (x-axis). Please help me. 

 

Thank you,

VG

You are trying to accomplish both one task (Y scale fixed range) and its opposite (autoscale) on the same chart. This is not going to happen.

 

If you want to use a waveform chart, the help screens which come with LabVIEW are really helpful. Give them a try.

 

You might want to visit the online tutorials listed below for getting started quickly.

That's what I thought too, but I need to check the graph for constant time period if the Y value dropping below certain value (DY/DT). Is it possible to write code for something like this?

Sure. I leave you with the same advice as above. That'll get you started.

 

Now, if you just want to fix your bottom OR top point with a fixed range to the other, that's quite possible, but it looks like you'll have to roll your own algorithm, I don't see any ready-made properties there. But it'll be easy
