I'm starting to use Imagine 2014 after a recent upgrade. The images I'm using have data values in the range of approximately -.02 to 350.0. The no-data values bordering the data has a value of 2 billion. The data displays white, nan black. It was easy to limit the values considered for generating a lookup table for display in previous versions but I'm not finding the tools now. What is the best way to get this data to display legibly in Imagine 2014?
