XY graphing

[dumbest_dummie]

I'm doing a simple acquisition of speed and current... trying to plot them in an XY graph.
Torque no Motor vs Velocidade da Mesa.
Problem is the graph is cleared (refreshed) every time number of samples ends(using Easy AI).
I wanted to keep the "history", watching the evolution of it.
Thanks in advance.

I assume that what you mean is that if you run the aquisition more than once you want to keep the samples from the previous runs on the graph...right? Like a chart but with XY functionality.

In that case you will need to make a buffer, e.g. a functional global style rotating buffer (If you can decide on the maximum number of samples to hold in the buffer you can work on a preallocated array and save lots of memory and get much better speed so that would be preferable).

Hello,

I think I understand what you mean.
Does the example I wrote below work, as a starting point?

Hi,

Actually i think they mean it like this.
