I expect the first picture to be similar to the third picture, which area of non-zero DPM conc can be displayed on the right side of the first picture.nLike the second picture, the area of non-zero DPM conc is really really big, but on the first picture just so little.nI don't know meaning you siad The first picture tells that dpm concentration is not pronounced and limited to some cells using that scale. The first and the third picture are always used by Auto Range in contour. The only difference between these two pictures is the different plane corresponding to my geometric structure. So, why did you think me used another scale ?nn
