[gradsusr] Plot data text in a grid instead of random

[Davide Sacchetti]

about second question: run basemap.gs before t2m (or display t2m again after basemap)


about first question use maskout, eg.: 
d maskout(t2m,t2m-32) displays only t2m>32
d maskout(t2m,33-t2m) displays only t2m<33
you can combine both:
d maskout(maskout(t2m,33-t2m),t2m-32)
(I haven't tried this command ... but the idea could be this)

Duh!  That was a dumb question on my part, and I apologize.  I have set ccolor working.  Two more better questions however.


Is there any way to do a set gxout grid at just 32 degrees F?  



I tried the following with set gxout grid:'set gxout grid'
'set gridln off'
'set cint 1'
'set cmin 32'
'set cmax 32'
'set ccolor 4'
'set digsiz 0.1'

'display skip(t2m,12,12)'


*where t2m = ((tmp2m - 273.15) * 9 / 5) + 32


The result is the full grid.


My other question is probably much more complicated.  I am using basemap.gs to mask out the oceans.  It is cropping the grid numbers by the oceans as seen here: http://jeffsweatherservice.com/grads/temp_US_2.png north of San Francisco and in southern Louisiana.  Is there a workaround for that issue?


'run 'basemap.gs o 202 1 H' (run after the lines above).


Thanks again!

The following worked very well:


'set gxout grid'
'set gridln off'
'display skip(t2m,10,10)'


Thanks guys!


Can you control the color of those numbers?  I can only get them in white.


 Sincerely,


Jeff C

You can also use a loop with 'draw string' to achieve this.

In addition to Davide's suggestion, you can use:


'set gridln off' to hide the grid lines


Use "skip" function to skip plotting every other, every third, etc. grid value

Hi GrADS Users,


Does anyone know if it is possible to plot data text in a grid pattern instead of random plots in GrADS?


For example, this is the grid pattern that I would like to use:

Instead, I am currently showing numbers randomly attached to a contour line:
