jqplot how to highlight a point
===

I have a set of already drawn jqplot plots, and I want to respond to mouse movement in any one of these plots simultaneously in all those plots. Thus, when the user moves over a data point in a plot, all  plots in this set that contain that data point should also highlight that point in their respective plots. And when the mouse is moved away, also unhighlight together.

Is there an already existing way to do such collective mouse highlighting? 

Alternatively, is there a way to drive point marking in a plot via user coordinates? Then I could imagine a plot-collection, and respond to mousemove event to maintain state of each member plot and drive highlighting/unhighlighting.

Thanks
