In general, this is a bit of a mess. The way that I do it is to use piecewise and set the min and mid to the same thing (this is what linear opaque was supposed to do). This way, anything that is over threshold has color, everything else is transparent. BTW, everything over the mid will be opaque. Values between min and mid will be semi-transparent. Some people like to much around with the min and mid to improve the look of the image, but really you want anything over threshold to be opaque.

Hi, Running FSv405 on RHEL5. Is any descriptive information available for threshold options in the configure overlay display gui? Specifically the bases for linear, linear opaque, and piecewise thresholds? Visually, the three options appear dramatically different. Are there specific datatypes each overlay option is designed to handle?
Many thanks for any information you can provide, Jenifer
