Hi,
I'm not sure how you want to use the data else in the model, but to reach the above chart, you need to get to a unified dimension (x axis).
I would manipulate the data a bit, split the rows into estimations, and completed rows.
In the chart, build two expressions
=count({<[Estimate / Complete]={'Estimate'}>}Date)
=count({<[Estimate / Complete]={'Complete'}>}Date)
with one dimension - Date
Below is a suggesion for the final table
| Date | Estimate / Complete |
| 5/17/2020 | Estimate |
| 5/20/2020 | Estimate |
| 5/23/2020 | Estimate |
| 5/25/2020 | Estimate |
| 5/28/2020 | Estimate |
| 5/18/2020 | Completed |
| 5/21/2020 | Completed |
| 5/23/2020 | Completed |
| 5/27/2020 | Completed |
| 5/30/2020 | Completed |
* it is not best practice to build flags based on text, you can just transform it to numbers, but it was just to showcase the solution
I hope it helps,
Eliran.
