[FEATURE] On Wait Stats screen, add hover/tooltips when hovering over a line #21

Description

Problem Statement

I'm part colorblind (but I think this will happen to other people too in complex servers with a lot of wait types.)

On the Wait Stats screen, when I'm looking at a line, I can't tell which wait type it is. I've tried hovering over points on the line and clicking on the line, but I don't see anything popping up or highlighting the name of the wait type.

Proposed Solution

Any of these would work, whatever's easiest:

  • When you hover over a point on the wait stats graph, have a popup tooltip that says what the wait type name is (and perhaps the number of waits and total wait time for it in that measurement point)
  • When you click on a point on the graph, same thing, pop a tooltip
  • When you click on a point or anywhere on the line, highlight the wait type name in the legend

Use Case

I know it sounds dumb, but I'm looking at this screen and I can't tell whether the big line is resource_semaphore, cxconsumer, preemptive_os_queryregistry, or preemptive_os_authentication.

(And until now, I did not realize the irony of naming this lab server "Colorful", but it's a gaming desktop with a bunch of LED lights.)

Alternatives Considered

Those cool Enchroma glasses that let you see colors.
