[gradsusr] Contouring / digits

[Eric Altshuler]

It looks like the data being displayed is actually geopotential, which is equal to g*(geopotential height), where g=9.81 m/s^2. To display geopotential height in dekameters, it is: 


'd 0.1*geopot/9.81'

If you just want to display geopotential height in decameters, just display the variable divided by 10, i.e., 
'd geopot/10' 

The contour labels will then take care of themselves.

Hello, 

maybe this is a really simple question :) 
I'm using the gme data from the GDS (German Weather Service) i can display the maps, overlay and those things 
all is fine but one thing i can't change at the moment. 

e.g. 500hPa geopot the values are between (Contouring: 50000 to 58000 interval 1000) 
thats what i get i'm trying to change the values to 500 to 580 (i know how to change the interval) 

I tried the function set clab ... but i can only add digits after the decimal point. 

Sry for my bad english hope you can understand me :) 

greetings
