Assign Color/Category to Data & Get Cumulative Count

Assign Color/Category to Data & Get Cumulative Count

Hello! I have a graph that shows a Lead Source, and I'd like to be able to color code these to show whether we consider the Lead "Warm" or "Cold".

Is there a way to say "If Lead Source = X Y Z, show as blue" and "If Lead Source = X Y Z, show as orange", and then show a cumulative count or percentage for the blue or orange category?
