It would be better to fix the axis so that we get the info by the position of the hisogram. Example: When you're at "Engineer", and then you click "Programmer"

It would be better to fix the axis so that we get the info by the position of the hisogram. Example: When you're at "Engineer", and then you click "Programmer", the histogram moves to the bottom, giving the illusion they're paid more, when in fact the labels on the axis also changed. The same axis for everyone to really bring the difference home.
