Display currently "selected" intensity value with raster plots

[KevinPoole]

Hey all,

First, a very cool tool. Appreciate you all making this available.

I am putting this as a feature request but it may really just be a request for slightly more detailed documentation.

All I want to do, is when hovering over a raster plot, to be able to see what the value is of any given pixel I am hovered over (the Z value basically, the intensity). If necessary I could do this in some sort of custom way with event listeners (at least, I think I could. I could do something similar to the mouse events example - https://sigplot.lgsinnovations.com/sigplot-2.0/tryout.html - and try to figure out where I am in the raster grid and then correlate that to the value in the source data) but it just seems like the sort of thing that sigplot must surely support out of the box and I simply can not figure out how. I would expect to be able to see a z (and corresponding dz value) in the bottom left of the plot window, or at least to be able to optionally toggle on such a thing, but again I can not figure out how.

Thanks in advance for any assistance you can offer!
