SSRS adding extra data into my histogram chart? RRS feed

  • Question

  • I am trying to create a chart that shows frequency distribution. I am trying to plot the following data which is on a table in a database, but I've made it into a simple temporary one here to be able to show what it looks like.

    CREATE TABLE #t (score int)

    INSERT INTO #t VALUES (25),(35),(37),(37),(38),(38)

    SELECT * FROM #t

    With this dataset on my chart it shows that I have 4 values as 37 instead of 2. 

    Does anyone know why I am getting extra data in my chart?

  • This is a very simple data-set and obviously should only show 2 instances of 37.

    I suspect your issue is something to do with the actual data set you are using perhaps.

    Can you elaborate on your actual data set and the graph it displays?

    Thanks for reading!

  • Hi carlosl-25,

    May I know what is your actual dataset like? Also, which type of chart are you using and how do you set the chart in SSRS? What expression did you use in the chart to calculate the frequency distribution? You could use SSRS expression to calculate the frequency like 

    = CountDistinct( IIF(Fields!score.Value="37", Fields!score.Value,Nothing) )

    Or you could add one more column in your original query to calculate the frequency. You could refer to Counting Duplicate Records based on a single field in SSRS

    Otherwise please provide more details about your report design, with some screenshots if possible. 

    Best Regards,
