You can use the XY graph instead of the normal Waveform graph.

Hi Everyone,
On my system i require a graph of pressure vs volume.
I have tried merging the data from the my pressure transducer and my crank angle encoder (volume) but i end up with a graph showing the two different data streams.
How can i alter the information so that it gives me a graph of pressure vs volume instead of pressure and volume vs time?
I have struggled on this for a while now and i cant find a solution.
Please help me!
Alex

Hi Alex,
can you show us the vi with the xy graph?
Thanks
Mike
Hi Mike,
Here you are.

Thanks Viskas,
Can you put these into an earlier version of Labview? Ive only got 8.2!
Thanks

Hi Alex,
I assume you are using the sinusoidal signals for experimentation. See the attached VIs - they should give you some idea of the usage.

Hi Alex,
here is your vi with some changes.

Thanks a lot Viskas,
you've done me a huge favour there, the stress was beginning to become a permanent fixture!
Cheers

Mike thats brilliant. Thanks.
I tried to get the data into the correct array/cluster forms for the XY graph but I just couldnt find the right ones.
Thanks a lot.
Alex
