Combo Chart with Line Issue

Hi DPCCGF ,

Based on the screenshot you provided, I created the following example data and created the calculated columns.

Would you expect results similar to those shown in the chart below?

Please let me know if I've misunderstood anything. 

If the the reply still not help you get the expected result, please provide some raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It would be helpful to find out the solution. You can refer the following link to share the required info:
