I am trying to make a graph of capability against demand. I have 3 columns: Demand (date), Coming available (end date) and Role.
I want to present on one graph the cumulative demand, the cumulative coming available and to be able to sort it by role.
In other words, I want to have a graph with the X axis of dates and Y axis of number available/demand (for each role should be two curves).
I hope it was clear! Thanks in advance
