Z-value tool-tip for intensity chart?

[JeffBuckles]

We would like to hover the mouse over some point in an intensity chart and have the tool-tip text give the numeric Z-value at that point.   I imagine I could do this with brute-force using mouseEnter/mouseLeave events and some calculations based on mouse/chart/window coordinates to modify the chart tool-tip value on the fly.   But is there a more elegant way to do this?   I could not find any chart properties or configuration to do this.

Thanks and Best Regards,

I would peobably update the tooltip.text on mouse move. it would be easier to not have it appear in the tooltip bit place a small indicator next to your intensity graph.

Late to the party....but using the tool tip might be a bit slow. Of course there is always the cursor legend. Using the mouse enter/leave and then update a cluster of indicators that are attached to the mouse works. See attached.
