    step size and the number of stages can be set, and they cannot be available at the same time.

  • Auto calculate the end value: This parameter needs to be used with the step size. Auto calculate the end value according to the set step. In some cases, the set end value is not appropriate, so that the result of (end value-start value)/step size calculation is not an integer, and the end value needs to be corrected. For example, if the start setting is 150, the end value is 1002, the step size is 100, and the end value is automatically calculated, the end value displayed in the color table is 950, not 100 2.
