Hi everyone,
I have been reading some previous articles about plotting using colors,
color tables and so forth and it is frustrating to say the least. I
only wanted to use IDL to do some scientific work but it seems that I
am more and more being sucked into IDL programming. To do things that
are simple, in MATLAB for example, requires a minor course and a panel
of experts in IDL. And so I come to plotting. I have seen many examples
where the plot script starts out like this:
PLOT, x, /NODATA
and then other parameters are plotted using OPLOT. I know what /NODATA
does but why is it done this way? Is it to avoid making long PLOT
statements? It seems, on the surface, unnecessary.
Cheers,
Sheldon

Not if "La Resistance" has anything to say about it.

I plan to do this as part of my magnimus opus work. It's
on the schedule :-)

Well, I think you're probably right about OG. But not about iTools. I mean, compare your
xPlot with iPlot:
- xPlot is easy to use.
- iPlot is non-intuitive and ridiculously complicated.
To be somewhat fair, xPlot doesn't do everythinbg that iPlot can ... but so what? 99% of
the time all I need is the functionality of xPlot.
I have no beef with OG per se, what I do have a beef with is not providing useful tools
that use OG. iTools (in my opinion and in my usage, not that of NOAA/UW/anyone else) will
never replace DG simplicity. I think it's ridiculous to expect non-programmers to spend
the same amount of time figuring out how to plot data as it is for them to
move/shuffle/reformat the data itself. In my case with DG the "data reformat"/display
ratio is probably about 90/10. With OG it's about 10/90 and with iTools it's about 50/50
(where, in the latter case a lot of the denominator is just waiting for the darn GUI to
display the data).
so much for avoiding the bad karma... :o(

Fair 'nuff. What I was hoping for was that your current object graphics codes (things like
xplot, xsurface etc, or their Catalyst derived equivalents) would be included in it.
