Hi there.
A friend of mine is having a hard time with XYY plots. I hope
someone could shed some light in his problem.
He has several columns of data (Y) which were
used to plot a XYY plot with the plane projections (XY, XZ, YZ).
That was the easy part.
Since each individual XY curve contains at least one maximum,
he would like to identify this position. Hence, it could
be possible to plot all these maximum points together, showing
a line connecting all peaks in the XYY plot.
Is it possible to do it ? This problem is far from trivial
because he has hundreds of XY curves.
I appreciate any suggestion you may have.
Thanks,
Sergio

Sergio, I think you're going to run into a "brick wall" with this. In order to overlay a line & symbol plot (which is either a 2D XY or 3D XYZ plot) on a 3D XYY graph, you would have to overcome a couple of seemingly-insurmountable problems. First of all, your plot data requirements are incompatible (how to simultaneously plot XY or XYZ data with XYY data?). Secondly, you can't add a second layer to an XYY graph, so that precludes combining different plot types (i.e. waterfall and line & symbol) by simply adding a second set of axes (and scales). So, as I see it, your only hope would be to create two separate graphs and then merge them; yet I tried several approaches to this but could not make anything work.
Certainly, a script could be written to loop through all of your Y data sets to find the maximum value, but the graphing part of the problem just isn't do-able. Could you maybe consider graphing the data in another way?
Maybe someone else has some ideas?

Thanks for the reply, Mike.
Well, we decided to do another approach for this problem.
We will just use the XYY graphs and leave the XYZ out of
the picture.
Thanks for the help !
