Problem with pie chart measure
Hi there,
I have created a measure that spits the area code if the area is contributing to 80% of total events otherwise it gives 'other' . Following is the meausre:
If I show this measure in a table visual, it looks like as follow:
When I try to drag the pie_percent measure into the legend field of the pie chart it does not drag. I also selected the pie chart visual, and checked the pie_percent measure, it went into the tooltip field. From there I tried to drag into the legend field but it did not work. Values field contains the [no of events] measure. Could anyone guide me on why is that happening?

Dunner2020 , This seems like a case of segmentation, You need to have this with an independent Table, You need to have area code table with others

Some area contribute to 80% in some weeks but they may not contribute in next week. Not sure how to create independent table in that case
Hi, Dunner2020
I think that Power BI does not support to use the measure to perform as legend or Axis of a chart, What’s more, pie chart is used to show the proportion of each category to the whole. According to your data, I can not figure out what’ your expected result clearly.
Would you like to post some sample data(without sensitive data) and your expected result? Thanks in advance.

v-robertq-msft , Thanks for the reply. Sample file can be downloaded from here . Expected output is as follow:
The above output shows the area code of those area which contributed to 80% of the total events. Areas that contribute to remaining 20% of events are shown as 'Other category'. Hope that would make sense now.
Hi, Dunner2020
Would you like to check the sample data you posted? I downloaded and opened the pbix file. But I can't find the ' Table' or anything linked to the problem you mentioned. Thanks in advance!

v-robertq-msft , sorry I renamed the tables. please check again
Hi, Dunner2020
According to your sample file, I suggest you use the calculated columns instead of measures, which can be placed into the pie chart and display the correct values, you can try my steps:
- Create these calculated columns in ‘Table’:
No of Events = CALCULATE( COUNTX(FILTER('Table 1', 'Table 1'[Date]<=TODAY()), 'Table 1'[Section ID]))Rank = RANKX(ALLSELECTED('Table'),[No of Events],,DESC,Skip)cumulative event sum = CALCULATE( SUM('Table'[No of Events]), ALL('Table'), 'Table'[Rank]<=EARLIER('Table'[Rank]))Pie_percent = var _total=SUMX(ALL('Table'),[No of Events]) var _percentage= [cumulative event sum]/_total return IF(_percentage<=0.8,[Area Code],"Others")- Create a pie chart and place fields, like this:
And you can get what you want.
