Hot/Cold FlameGraph Support(Mixed)

This type of visualization combines both on-CPU and off-CPU flame graphs. This visualization provides a comprehensive view of the performance data by showing all thread time in one graph and allowing direct comparisons between on-CPU and off-CPU code path durations. The hot and cold functions are shown together in the same graph, providing a clear and concise view of the performance of the program.

The darker colors indicate on-CPU and lighter colors indicate off-CPU
