Highlight Frames of Interest

[groundwater]

Just curious if this ability is already included, or you have a suggestion on how to do this.

I would like to highlight frames from our library in the flamegraph, for example by drawing them in blue vs orange.

This would help me identify where our code is actually doing things, and where it's causing trouble.

Good idea! The only highlighting that's built in right now is highlighting by percentage of time spent in a given function. That's what it does by default. To do that, we vary the saturation of the main color, but we keep the hue the same. We've talked about using separate hues for separate libraries. It should be pretty straightforward, since the library name is part of the symbol's full name.
