    Hi acbg,

     

    Based on my test, you should rebulid your visual here. As I can reproduce your issue here. Or if you just add rows in your data source, then everything should go well.

Hi acbg,

 

I made a sample as below. We can Pivot the Month column based on the sales column.

 

 

Here is the M code in power query for your reference.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8s3PK8kwVNJRAuFEpVgdJCEjIE5CFTIG4mRUIRMgTkEIgTSZopoFEjJDNcsIamMyqpARqlnGUBsTUYVMUM0yxrTRGNNGY4TrYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Month = _t, sales = _t, users = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Month", type text}, {"sales", Int64.Type}}),
    #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Month]), "Month", "sales", List.Sum)
in
    #"Pivoted Column"

For more details, please check the pbix as attached. If it doesn't meet your requirement, kindly share you sample data to me.

if we use the actual month name instead of Month 1 then it does not work.

 

For example: Instead of Month 1,Month 2, Month 3. Use Jan, Feb and Mar.

 

Then re-name the months as Apr, May, Jun. in the dataset and reimport it. M code works when we pivot it with new column names as Apr, May and Jun.

 

But the end graph/table in Power BI do not auto-recognize the change in column names from Jan, Feb and Mar to Apr,May, Jun.

 

It errors out as its unable to find Jan, Feb and Mar columns.

      v-frfei-msft Thank you for the response.

       

      I was hoping there is another way of automatting it.

       

      I have the months changing on a weekly basis and would like for it to be automatted instead of fixing it each week.

       

      Since I can't find a automatted solution, I have went back to calling the months Month1, 2 and 3 instead of the actual names.
