Solution

You have two options:

  1. Use a library like KineticJS which abstracts the drawable shapes into objects and provides nifty methods for binding them to mouse events. This has the benefit of minimizing the work required by your side, therefore allowing you to concentrate on the functionality itself, and not reinventing the wheel.

  2. Roll your own solution, much like someone does when he/she created a library like the one mentioned above. Design some abstraction for your shapes (in this instance some kind of a Bar object) that encompasses the relevant features (notably the x,y,w,h) and on canvas mousemove-event, bruteforce through all your bars and calculate whether or not the event mouse position is within a bar or not. Then act accordingly, e.g. redraw the bar in new color. Of course you'll have to handle mouseout as well (to color it back and the like).
