The unit of x-axis is hours (h), and there are 24 hours in total.

The unit of y-axis is millions (m).

How do I calculate the area under the red curve in the image in units of m*h?

Important UPDATE

Only the image is readily available (not the data), and I want to calculate the area programmatically.
