[IDV #EKY-504245]: Jython script for 2D plot movie

Hi Roman.

Sorry this took so long. We have been somewhat understaffed  this week and 
last. Things should be returning to normal shortly. I was able to get the 
ncfile in question.

Since this is Jython you may have to get your hands dirty by looking at the 
actual IDV source. I try to answer some of your questions here:

Display unit: dc.setDisplayUnit("K")

Color range on the color table: Do you want to create your own, or use a 
prebuilt color table? You could do something like 
dc.setColorTableName("Temperature").  Otherwise, I suppose you could create 
your own color via Jython.

In your script, it looks like you are already modifying the contour parameters. 
Is there something wrong with that?

Setting the level ought to be possible, but I have not figured out how to do it 
since the PlanViewControl.setLevel method takes an Java Object type. I do not 
know how that Object is instantiated. I am still looking into that.

For the time range, there is a dc.setDataTimeRange. You will have to figure out 
how to properly construct a DataTimeRange object to supply to that function 
call.

About the order, Python is an imperative / functional as opposed to a 
declarative language so yes order is important.

This is probably enough to get you started. Let us know if you have more 
questions.
