Hello, does anyone know how to make the plot on a predefined unit size?
In my file 20 is almost equal to 60, i dont want that 
Disappointing as it may be but there is no support by the program to do so. All you can do is to resize the plot region until (by optical inspection only) the axis are equally scaled. Drag it by left clicking and holding at the center of the right or bottom border.
BTW, you can change the first, second and last value on each axis to scale and assign the tick interval by clicking on it. Unfortunately it does not always work as expected.
