[Gnuplot-info] swap x/y of 3d plot

[Peter C. <pe...@ho...>]

We plot a waterfall using the below pruned script.
Normally our data looks like:
      t1,t2,t3,t4,t5,t6...
f1, v1, v2, v3, v4,v5, v6
f2, v1, v2, v3, v4, v5, v6
...
With the rows being frequency and the columns being timestamps and V 
being the value plotted

This all works fine, except we have one dataset that has rows and 
columns reversed so that it looks like:
      f1, f2, f3, f4...
t1, v1, v2, v3, v4
t2, v1, v2, v3, v4
...

I cant figure out what I need to change in the script to get it to plot 
correctly.
