How do I determine the number of plots on a waveform graph?

[Terry_B.]

How do I determine the number of plots that have previously been plotted on a waveform graph? I am loading dynamic data from a file. If I convert to an array and size it and there is only one plot, I get the number of data points and I don't know how to tell the difference.

Usually by reading the graph terminal or a local of it and determining the first or second dimension (not sure which at the moment) size of the resulting 2 dimensional array. If it is a 1 dimensional array you have either only one plot or an array of clusters each representing one plot. But as these data types are determined by compile time, there shouldn't be a problem with this causing ambiguity.

Sounds like you really want to know how many waveforms are in the dynamic data. In your "Convert from Dynamic Data" node, change from "1D array of scalars - automatic" to "1D array of waveform" and then use Array Size on that.

Thanks for deciphering my question properly! That is exactly what I needed. Much appreciated Roy.
