This Bar chart uses the custom RGraph draw event to add highlight to each bar.There's a canvas version of this chart here. The draw event is used to run some code which, using the coordinates of each bar, adds a semi-opaque rectangle to the left-hand-side of each bar. There's also a shadow and the background grid is customised.
