Line Chart to Show Daily Increase

[mrouton]

I currently have the following data and I'm trying to create a chart that will show a diagonal increase from the Start Date to the End Date increasing each day by the Points Per Day (for example: for version 1, day 1 would show 4.08, day 2 would show 8.16,  day 3 would show 12.24, etc.)

Version       Start Date       End Date       Total Points       Number of Days       Points Per Day

1                 8/2/2018        9/8/2018        151                   37                             4.08

2                 9/9/2018        10/16/2018    160                   37                             4.32

I have created a Measure to use as the value for the chart, but it is showing a horizontal line of just the Points Per Day and not a cumulative increase per day when I use a slicer on the Version.  I would appreciate any assistance with the DAX to generate the diagonal daily increase that I'm looking for.

Cumulative Points = Sumx(filter('PointsPerDay',max('DateDimension'[DateKey])<='PointsPerDay'[End Date] && MAX(DateDimension[DateKey])>='PointsPerDay'[Start Date]),calculate(sum(PointsPerDay[Points Per Day]),filter('PointsPerDay',max('DateDimension'[DateKey])<='PointsPerDay'[End Date] && max(DateDimension[DateKey])>='PointsPerDay'[Start Date])))

@mrouton,

You can firstly create a custom column in Query Editor to list all dates between start date and end date, then calculate the daily increase usin DAX. For more details, please review attached PBIX file.
