Displaying realtime x-y data ?

[m-s]

I want a realtime plot of (x,y1,y2,y3) pairs where x is the excitation level in an experiment (equispaced, ranges known) and y1, y2 and y3 are the detected responses.

If I use a waveform chart (which uses a waveform o/p) I can wire the spacing between x's (delta x) to dt. However, t0 is required to be a timestamp. I am using stacked charts to track y1, y2 and y3 simultaneously (they are of different orders of magnitude and thus cannot be put in the same plot).

Is there a way to plot data in realtime (as it is measured with both the axes autoscaling as it grows) ? I don't care if it is a waveform chart or a graph.

m-s,

Not sure if I fully get what you are aiming for, but it sounds like an XY graph may be what you are looking for, where you can have your excitation value on the x axis and the response on the y axis.

Is an X-Y graph capable of handling streaming data (point by point) from a running experiment (its available as a cluster).

You have to store the previous data in a shift register and update the XY graph with that plus the new data.

However, the Build XY Graph Express VI does that for you.
