Hello ; I don't see any specific option on the wave config but you can try to change the Height value as it shows the below picture Or you can locally zoom in an area in your plot by selecting and dragging the mouse from left to right and zoom out by dragging from right to left. 

Yes, this is nice, but it would be better to be able to change the scaling of the axis from logarithmic to linear (from dB into V or A). The same applies for the frequency axis, that should also be able to be scaled in a linear way. In LTspice, this is also possible without a large effort.

We have to have the posibility of changing the max and min values of graphics. For example, I have a power supply of 12V and a voltage comparator, sometimes it has 12V at the output and sometimes 0V, it depends of the input values and the wave form plot show me from 4V to 6V, I do not know what is the real value at the output of the circuit.

@robelman26604, The Waveform plot should auto scale to show the max and min extents of the signal in the time interval between the selected simulation start of display and the simulation stop time. If you only have a 4V to 6V vertical scale then that suggests that your choice of simulation times needs to be revised or the simulation is not behaving the way you are expecting.
