Initial Request
----------------------------------------------------------------
I realize the plotting tools are only to aid in determining what data is available in a theater of interest and not be presentation quality. However, when I plot this on our Linux system (X windows), the image back ground is checker board pattern that makes it hard to read the underlying data, see attached. Is there anyway to get this plot with a uniform background?
Thanks

Bob,
That checkerboard pattern isn't real. That's an artifact of the way
ImageMagick is displaying the PostScript file. The image has a
transparent
background instead of a white filled background. ImageMagick displays
that
as checkerboard. And notice that it's in portrait instead of
landscape.
Since you have ImageMagick on your machine, I assume you also have the
"covert" command available. If so, I'd recommend running the following
command:
convert -rotate 90 -background white -flatten obs_plot_06z.ps
obs_plot_06z.png
Then display the resulting .png file. It's funny, I've typed that
command
so many times my fingers know it better than my brain does!
Alternatively, if you have ghostview (or gv) on your machine, that
will
display the PostScript files well.
This actually reminds me of a new GitHub issue I created last week.
The
idea of making plot_point_obs more configurable as a way of
understanding
the data better:
https://github.com/dtcenter/MET/issues/1528
We didn't identify this as a very high priority issue. Do you think
you'd
find these enhancements useful?
Thanks,
John

John, thanks for the tip - I will give it a try. Any enhancements to
the plot_point_obs would be beneficial to us. One thing that would
be verify helpful is to have a terrain map background or have a filter
to display observations in relation to their elevation.

Thanks for the feedback. I added that as a comment to the GitHub
issue.
