Hourly Temperature when pressing on the graph

I know there already were a few (1,2) suggestions for adding hourly temp info in the graph view.
I find myself wondering about the exact hourly temperatures a lot.
My suggestion would be to highlight temperatures for a specific hour when pressing and holding its respective data point on the graph.
That way the UI stays clean but you still get precise info when needed.

I like this idea. It fits the design of QuickWeather.

Unfortunately, I am not too sure how I could implement it since currently the graph is a simple image. I'll think about it when I get more time to work on QuickWeather
