Questions

tl;dr = Why can’t I use DateTime on the YAxis for any XY type plots (Line, Scatter, etc)?

I have created a Heatmap solution that displays data with Time along the Left and Frequency along the bottom. This works great, and I don’t really want to refactor it.

Now, I am trying to plot some observations over the top of the heatmap, in the form of (value, timestamp). Then I run smack into the limitation mentioned in the title of this post. Can someone please explain the limitation? Isn’t the DateTime just a long (which can be a double)? You already do work at the double level (as evidenced by the AsDoubleRange() method on all of the Range objects), so why not just convert to Ticks, and then convert back?

I think I can solve my issue by adding axes, rotating them, managing their visual range… Just seems like a lot of work for a relatively arbitrary (at least on the surface) limitation.

Thank you for any insight you can provide.

Mike.
