Plotting pump flow against RPM using xy graph

[MogaRaghu]

I want to plot the output flow from a pump versus the shaft rpm. How to achieve continuous plotting using a XY graph ?

I read through the posts here and in one of that a refernce was made to the Variable-Timechart.vi example as a possible solution for this scenario. Is that the only one way out ?

As an added information I am using a M- Series card that supports only the NiDAQmx drivers.

Some tips to tide over the problem would be helpful.

Thanks

Hi Raghunathan,

You could use waveform charts but they have to have a constant delta t for the time axis so Variable Time Chart XY.vi seems to be a better option.
