Power BI Gauge Visual Issue

I am using the gauge visual to display a calculated measure of the rank of a score, with the max value set to the number of areas.

This seems to be working fine with some areas, but sometimes the gauge visual seems to add 1 to the calculated rank. See picture of incorrect gauge, and table above showing calculated rank.

Incorrect Rank being return

However on the same series, the gauge shows the correct rank:

 

The fact that the rank returns correctly in the table, and additionally elsewhere in the report on line charts, it makes me think it is something to do with the gauge visual. Does anyone have any ideas?

    Hi,

     

    i think your Gauge is showing the total.

    Hi StephShadwell,

     

    Can you share how you created the gauge visual and the calculated rank?

     

    I noticed your first visual displays the wrong total of rank, just like the gauge visual. I would assume that something is being summed with East of England.  Are you using a slicer to filter the data shown in your screenshots? 

     

    I would also change the default summarization of rank to "Don't Summarize", because rank is something we generally do not want a total of.

    Hi StephShadwell ,

    I think it should more be related to your filters you set in measure formula, it seems like its calculations only interact with specific fields. Can you please share you measure formula with some sample data? It is hard to troubleshoot your issue without any data.

      Hi,

      Just to confirm, i have checked there is no default summation happening on the rank measure, and this is greyed out to don't summarise.

       

      Apologies, i realised the table i included was probably not that helpful, as it was interacting with all the filters (see a better screenshot below):

       

      As for the calculated rank measure, see DAX below:

      Gauge - RankCalc = IF(HASONEVALUE(vLKP_LSOA11_tidy[GeographyName]), RANKX(ALL(vLKP_LSOA11_tidy[ParentGeographyName], vLKP_LSOA11_tidy[GeographyName]), [CalculatedScore], ,DESC))
       
      I have set up the gauge, using the above  measure in the value field, and then the maximum is set to the sum of n (which is a column in a table joined that contains the number of areas within the geography type.
       
      I have done a new table that includes the calculated score, to confirm the ranking, which confirms the ranking in the above table is correct based on the score.
      The calculated score is being calculated using the following DAX:
      CalculatedScore = IF([MeasureCode] <= 7, DIVIDE(SUM(IMDTidy[PopulationWeightedScore]), SUM(IMDTidy[Population]),0), DIVIDE(SUM(IMDTidy[PopulationWeightedScore]), SUM(IMDTidy[Population]),0) * 100)
       
      I hope that helps, if you need anything else, let me know.
       
      Thanks

      Steph

        HI StephShadwell ,

        I think it may be related to all function, can you please share pbix file with some dummy data for further test?

        Notice: do mask on sensitive data before share.
