  • Subject: [IDV #ZMC-625222]: get data by using script

Hi,

I cannot replicate this problem. For example, when I do:

d1 = makeDataSource("ruc.nc")
d2 = makeDataSource("subset.nc")
f1=getData("ruc.nc","T")
f2=getData("subset.nc","T")
createDisplay('planviewcolor',f1,"T")
createDisplay('planviewcolor',f2,"T")

The displays have different data. Not sure if you know about this but you can 
use the interactive Jython shell (Edit->Formulas->Jython Shell) to be able to 
easily type in this kind of jython and see what is going on.

I just answered a colleague of your's with the same question:
