How do I update a waveform chart with multiple plots one point at a time?

Hi,

I am updating multiple plots one point at a time.  That is, every time I update the chart I have a value for one of the plots.  If I put in a cluster with NaN for each of the charts except the one with the data I can only get individual points on the chart.  I would rather have them connected.

Any clues?  The only thing I can think of is to delay the update and do interpolation between samples - too complicated for me.

Thanks

Are the points within a given plot equally spaced in time?  If so, perhaps you need to maintain your own history of the data and used a waveform graph rewriting the history data to the graph each time.  If the points are unequally spaced, then you will need to do it as an XY graph.

Thanks Ravens Fan,

The points are not equally spaced.  I'll give the xy graph a try.
