Hi Roman. Try dc.setDisplayUnitName("K") although I have a feeling this will not do exactly what you want. dc.setDisplayUnit is actually protected I would suggest learning some Jython and figuring out how to call into Java. That would be a good exercise. Next, I would start looking at the IDV source and looking at classes like DisplayControlImpl. As we move forward, specific questions are best, rather than a list of general questions. -Julien > Hi, > I have posted my IDV support issue below. > > -Roman > > > > > On 11/18/10 12:19 PM, Roman Kowch wrote: > >> > >> Julien & Yuan, > >> > >> I'm still having problems with writing a jython script to create an > >> image from the file IDVmitmodel2.nc.
