autorange of the spectrum view

How can i disable the auto range when i open the spectrum view

Hi,

this cannot be disabled. The spectrum should always be fully visible.
By default, the value range only increases and if you have hovered the mouse over the areas with high values the value range keeps pretty constant. If you want to reset the value range, you can press the SHIFT key. This resets the value range to the current spectrum.
