    Bin results by count

    Scott Henry

      Hello -

       

      I'm absolutely brand new to Tableau. I know this must be a very simple question -

       

      I have a dimension of text named 'sources', like 'Fair', 'Email campaign' etc. Each 'source' has a count of records for each given time period, let's call it a quarter. My goal is to create two bins, 'major sources' and 'minor sources', where the major sources are listed by name, and the minor sources are just referred to as 'minor source'. Basically, I just want to alias all the names in the dimension that fall under a certain threshold.

       

      The goal end result is a bar chart, where there are a series of bars for the major sources where height = count, and one bar for the all the minor sources combined.

       

      Again, I know this is probably very simple, and I'm probably missing something obvious. I've tried multiple calculated fields, ie, IF COUNT(Source) < 10 THEN .... , but I end with with a measure rather than a dimension (probably because the calculation is dynamic, based on quarter). If I try to use the [source] field in the calculation, I run into errors like 'cannot mix aggregate and non-aggregate'.

       

      Hopefully this is clear! Again, I'm brand new to this!

          Hi welcome

           

          here you go - try this

          IF sum([Sales])< 100000 then "Group 1" else "Group 2" end

           

          Where you can fill in the values and names

           

          Let me know if this helps

          Jim

            Scott I meant to attache this - you end up with something like this - the field is listed under measures but you can use just drag it up to rows etc

              Scott! Welcome to Tableau! We can certainly help you out.

               

              Personally, I'm finding it hard to understand what you'd like to do - especially without some sample data. Could you possibly add some mock-data or a tableau workbook (.twbx) Packaged workbooks: when, why, how 

               

              Binning can be done in two ways. either by dragging a single measure to the view, and using the "Show Me" tab:

              or straight from the measure:

               

              You may also want to look into groups or sets:

               

              Now I may be wayyyyy off... Perhaps I'm just misunderstanding what you'd like to do.

               

              We're here to help!

                You guys are great! Thanks for spreading info to the newbie!

                 

                Jim - I feel like I'm getting close. I've gotten to the 'Group 1' vs. 'Group 2' , but what I'd like is to have 'Group 1' vs. 'Appliances' , 'Accessories', 'Binders' , so I suppose 'Group 1' should be summed together, and each name separately in other group.

                 

                I'll try to clean some data for publishing to help explain.

                  Scott there is another way if you know before had what you want to group  and what you want to leave separate

                   

                  You can simply right click the dimension in the try and select group - a window will open and you can select the member you want to group then click OK

                   

                  You can then rename the group

                    Thanks Jim,

                     

                    I suppose I don't know which categories go in which group until the results are totaled. I'll get a mock up workbook and see if I can better explain. Thank you guys for helping!

                      Okay - I think I figured out one way to solve this! Thank you guys for your insight!

                       

                      First, I used the 'Sets' feature to create a set on the Condition -> By Field: Number of Records where Sum < 10 (my threshold). Of course, this just provides an In vs. Out.

                       

                      I then made a calculated field: IF [Set] = False THEN [source] ELSE 'minor source' END

                       

                      That gives me the total for all the 'minor sources' versus all the others! I think that's what I was after! Thank you so much for helping!
