[12/24] kernel-shark: Add combo point to Mark

Commit Message

Yordan Karadzhov Feb. 1, 2021, 5:23 p.m. UTC

KsPlot::Mark uses colored point to highlight the selected trace event
on CPU and Task plots. Here we add a combo point that will highlight
the selected event in Combo plots, like "Virtual Combo" for example.
Those Combo plots will be introduced at the level of the GUI code in
successive patches.
