Plotting x,y,z,p data

[JBlackhole]

To all

I have an input csv file of x,y,z,p data. Where x,y,z are the coordinates of nodes and p is a number (pressure)

I can create a scatter plot of the the x,y,z, see atttached, but cannot create a plot of the value p (as a function of the nodes position). Is there a way of doing this?

Thanks

You want a 4D plot? That's not possible. In theory you could have an xyz surface, with colors on it that represent p, but Mathcad can't do it (it's been asked for, but we don't have it).

It is a function of 3 arguments...

I use not a surface plot but a set ot 2D plot.
