Hi All,
The data range of color map and color leged does not match if I do follwing procedure.
1. check the checkbox of “Use log scale when mapping data to colors” in color map editor
2. uncheck the checkbox
3. click the “rescale to data range” button
Although there are minus value in the displayed data ,the minimum value of color legend is set to zero.
On the other hand, the minimun value of color map is set to minimum value of displayed data .
Could you please let me know how to fix the color legend?
Thanks in advance.
