I am plotting 2D functions on Sage, and I would like to move the values displayed along the $y$ axis (the ticks) from the left of the axis to the rigth, because they bother me there. I had a look and I think this can be done in Python with matplotlib (using set_tick_params() or set_ticks_position()) which is included in Sage, but I am not sure of how to combine a region_plot() from Sage with this axis modification.
