[gradsusr] Plotting xcbar.gs Even When There is No Valid Data

[Perry, Aaron]

Thank you very much for the quick reply, Jennifer!

So to reiterate, I need to save the 'q shades' output from a forecast hour with valid data and then use that same output for a forecast hour that has no data, (instead of running 'q shades' again on the forecast hour with no data) therefore preserving the desired colorbar on the plot.

The colorbar scripts generally run 'q shades' and then parse the output in the 'result' variable. I have worked around this by setting up a plot with the contour levels and colors I want, then saving the output from 'q shades' in a script variable for later use:
'q shades'
_shdinfo = result

Then I append a modified copy of the colorbar script as a function in my main drawing script that uses _shdinfo instead of running 'q shades' again.

Good Morning All,

I am trying to figure out a way to plot xcbar.gs even when there is no valid data in the grid to plot.

For instance, there is no GFS precipitation values in a certain domain, say the Northeastern US, for Forecast Hour 12. xcbar.gs says that there is no shading information and therefore, does not plot a colorbar for that one frame. I want to have that precipitation colorbar plot for every frame regardless of if there is data in the grid or not.

I've tried going into xcbar.gs to see if there is an override to plot regardless of valid data or not but, there doesn't appear to be.

Any and all suggestions would be greatly appreciated.
