Hi everyone, Having just recently taken a stab @ ISL scripting, I can attest to its utility and potential ... and it does make for much nicer looking text rendering. But the key word is "potential" ... it currently lacks some basic features of scripting languages ... such as the ability to set an integer value and then increment it (very useful when creating an animation loop). Please keep these comments coming. The IDV Steering committee, on which sit both Don Murray and I (apologies if I forgot anyone else on this thread), as well as the Unidata Users Committee (which I chair) depend on these use case assessments (good as well as "needs improvement") to give guidance to the Unidata folks (who also appreciate hearing these real-world use cases too). The font issue *has* improved in the past ten years ... one can choose from a plethora of fonts installed on the host system, and the user has much more control over placing the text strings which use the selected font when labeling contours. That capability came about via emails such as this thread which Paul Graham started (thanks, Paul!). Now we see a good call from the user base that can hopefully motivate further improvements towards publication-quality graphics. On a side note, I'm very excited about the changes upcoming in the next (version 5) release. Memory usage, a big problem with hi-res imagery and grids, has really improved, as well as progressive disclosure as the user zooms into a region of interest.

It would be nice if this could be made easier for everyone. Many people to whom I have suggested this option have decided against it. They only want to use the UI.
