I need someone, anyone, to explain in plain English how to display
logarithmic data in object graphics. I have stared at the
obj_logaxis.pro code in the examples directory and I still can't figure
out why their stuff works and mine doesn't. I can't stand how RSI
didn't put any explanation into their documentation, but just included
the example code (poorly indented code at that -- at least in the
manual itself).
In my last failed attempt, the Y axis and the data are smushed against
the bottom of the plot. In previous attempts, I managed to get the
correct log curve in the plot, except the axis was scaled incorrectly
and I had a few experiences with the infamous "infinite plot range" and
stuff like that. But no matter what properties I get and set, I can
never seem to make things work. I already have code which works great
for linear axes. I just want to add a Y axis log capability to this
code -- that's all, nothing more.
If this goes on for much longer, this might take the "frustration time"
record away from when I first learned about 8-bit and 24-bit colors in
direct graphics. ;-)
