Dashboard Chart Summarizing Project Plan

Hi Community - we have a basic requirement to show the number of tasks forecast to finish each week against the baseline plan. For example, this is my Project Plan:

Task Name Finish Plan Finish

Task 1 3/1/2021 2/22/2021

Task 2 3/8/2021 2/22/2021

Task 3 3/8/2021 2/22/2021

Task 4 3/15/2021 2/22/2021

I would like to generate a line chart with two lines on it like this:

I can only think of two ways to do this right now, both of which are essentially to manually generate the cumulative counts for Finish and Plan Finish for each day in the chart's x-axis. Either way a ton of extra columns in the Project Plan sheet or with a separate Grid sheet that looks like this:

Is there a better way to do this?
