WebA flame graph is a visual representation of the stacks and stack frames in your application. The graph plots all of the functions in your application on the X-axis and displays the stack depth on the Y-axis. Functions are stacked in order of ancestry, with parent functions directly below child functions. The width of a function displayed in the ...
