I want to make a graph where I have a dates, each one represents the end of month, and a measures the situation of the portfolio (accounts receivable) and on the other hand the sales.
Accounts receivable is at the end of the month, since I cannot accumulate these values daily because it would create a distortion, while sales need to be accumulated each month so that it reflects the data and metrics that I need to present. How can I make the graph?
