Yes, it seems like the [XY]_LOG keywords are broken.
In any case, I can't seem to get a log axis on
an iPlot by setting either of these keywords. And
worse, the logarithmic selection on the axis property
sheet is grayed out and unavailable for the axes.
I don't know what to make of that. I guess I would
check with RSI.

There is no built-in command to do this, I don't think.
But it seems fairly straightforward to me to build your own.
I just threw my 2D array into FSC_SURFACE and selected
parallel X lines from the Style menu and had almost what
you describe. You want your plots in a different plane,
and you want log axis scaling, but having a rotatable
plot is nice. Probably a two hour job if you
start with something like SIMPLE_SURFACE on my web
page. :-)
Cheers,
David
