julia> #= By default, "ZOOM" mode is active. This means that
now you can select some part of the plot with left mouse
button.
Right mouse button will return you back to the previous
state.
And try mouse wheel also.
Button with a "hand" - it's a "pan mode". It will shift all
the plots, but not change scale.
"disk" button - allow you to save image to a file
"[]" buttom means "make square axis" i.e. make equal scale
for X and Y axis.
Real magic is in left and right buttons; see below about it.
