## min

   'min' <value> ['e'|'f'|'i'|'l'] ['l'|'u']

This keyword is used to define the lower value in the scale in the menu area (see figure 2). The number representation can be changed between exp, float, int or log10 for which the scale is restricted to positive values. For example

min 0 i

will set the lower value to 0 and the representation to integer. A third parameter "l" (lock) or "u" (unlock) can be provided which locks the scale to certain max or min values. The selection of a different dataset will not change the scale.
