I keep getting stumped unfortunately.
I have 2 tables. A full list of all configuration items (text field) in one table, and a second table which is a list of config items that were updated last month. I just need a simple % of Config items updated last month.
The two tables are "Config Metrics - Updated" (the ones updated last month) and "All CIs" .
I created a new measure
% Updated = (count('Config Metrics - Updated'[CI Identifier]) / count('All CIs'[CI Identifier])) and put in format %. If I add that number to the chart or table, it comes out correct - around 9%
I then try to apply this to a line chart, so that I can have the x-axis as the month. I have a column in both tables called "Reporting Month". When I add that to the x-axis, the percent jumps up to 112%. I don't understand why adding the month column to the X axis would affect this. I've done several other line charts like this without any problems - but this is the first time I've had to do the calculation using columns from 2 different tables. Am I missing something? The relationship between the two tables is based on the CI Identifier field - and it is a one to one. (The CI identifiers are all unique)
Alternatively, I do have the updated by dates in the "All CIs" table, but I couldn't figure out how to make it reflect a percentage updated for month to month. I created the bin's for the date in monthly separations, but I still can't get it to reflect just the percent of the total value, rather than the selected value (as soon as I select only January, it jumps to 100%). This issue seems to be a common issue I've not been able to properly solve.
Sorry for all the posts - I just have a quick approaching deadline for creating many reports.
