'max' <value> ['e'|'f'|'i'|'l'] ['l'|'u']
This keyword is used to define the upper value of 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

max 1100 i

will set the upper value to 1100 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. The specified value defines the highest value of the last box. See also ”maxr”, ”min”.
