Drawing a window in a chart, and have a new array of the chart data in that windowed area returned.

[jeclark2006]

1. Is there an option to dynamically draw a window using Chart.js functions, over data that has already been plotted on the canvas?

2. Once having drawn such a window, cause an event handler with the window coordinates as parameters.

I do notice that there I hover the cursor over a plot, the y-value is displayed but not the x-value. Is there some option for both x and y to be displayed in the hover event.

I'm looking at code I did not write to see what additional functionality I need, or select another graphics package if this one is not capable of what I need.

Thanks.
