I am new to Power BI and have some success with basic calculations and reports only with 2x Global Knowledge training classes and advice with others within this Power BI forum.
Laterly there been a request to produce a control chart using 2019 rejected results based on previous 2018 rejections. Needless to say I can easily produce this type of request using excel and to be honest currently I am importing excel figures to achieve this request .
I am just not satisfied having to use excel and would love to see a real solution in Power BI.
Below is a snapshot and example of data being used to product the control chart, Any advice & help would be greatly appreciated,
