Re: [idvusers] Contour plot defined by two variables (into defined ranges)

Dr. Traveria --

I assume you want an isosurface at the 95% Relative Humidity level,
and color this with temperatures between 0 and -20?  Chris Herbster
(Embry Riddle Univ) has done similar work.  Here's what you do:

1. select the gridded data set in the Data Chooser
2. select 3D relative humidity in the Field Selector, along with the
Display type (isosurface colored by another parameter),
     and for the other parameter, select Temperature
3. Pick the times you want and region, if necessary
4. After the display, set the isosurface value to 95% and then you can
change the color range on the temperatures to be -20 to 0.

I hope that is what you are asking about....if not, please let us know.

Best regards,

tom
