variable time multiplot XY chart

[MancPablo]

Gurus,

I have reached the point in needing some help. Attached is a simulation of what I am doing. The part I need help with is quite clear...

I need to plot 2 XY graphs: data vs a variable time (although in the example it is fixed). One chart has a single plot, the other 2 traces. The graphs have a fixed length, behave like a waveform chart, except it is first in first out.

The graph in the top level VI labelled Total SA is a single trace plot. When running I can right click and select 'clear graph'  and it removes all the data in the buffer.

How can I achieve this with the mutli plot (2 traces)  XY graph labelled Total Mass in the top level VI?

Paul.

Hi Manc Pablo,

Having read through your problem and taken a look at your code I would suggest that you investigate the piece of example code called "XY Graph.vi" in the LabVIEW example finder.  This demonstrates the correct coding practice for plotting two traces on a single graph.

I hope this helps but if not please reply with any problems you are having integrating the example code into your own vi.

Regards,

Tom
