Avg line on bar chart not displaying the same value as the measure

[nleuck_101]

Hello All,

In the image below, I have a monthly rate of 3.57% as an Average Line in my bar chart. The average monthly rate is a measure but when I display that measure in a display card I get 3.55% as the monthly rate. Can someone please explain why I would have two different numbers for the same measure? I expected to see 3.55% on the bar chart just like the display card.

Thanks!

I was able to figure out what was going on. The average line in the bar chart is adding the percentage for every month and dividing by the total months. This is not an accurate way to get the monthly average over a time frame in my opinion.

Would you provide more details on the measure and data you're using?

The the measure is Total Terminated / Avg HeadCount. I'm working on a Turnover Rate. Just not sure why it's showing two different numbers.
