[IDV #WWV-305170]: select data source by using script



Hi,

Yes. Look at the routines in the shell.py jython library:
http://www.unidata.ucar.edu/software/IDV/docs/userguide/tools/JythonLib.html#shell

In particular you can call:
def getData(dataSourceName=None,dataChoiceName=None):

This finds the first data source if the dataSourceName==null. Else it tries to 
match on the data source name which can be set in the data source properties 
dialog.
