Represent null data as zero in line chart

Hello, 

 

I'm building a line chart that represents the evolution of the count of some Value (y axis) depending on levels. As you can see: 

 

- The x axis starts in February 2021, with Value=3 in level 0 (thus, there are three items with value 0). There are no items in level 1 and 2.

- In April 2021, data with 1 and 2 level appears, and data with level 0 decreases. 

What I'd like to obtain is a line chart where level 1 and 2 are represented from february 2021, with value=0. Graphically, this is my desired output:

 

 

I've tried adding "+0"  to the measure that I've configured in my  y axis, but it's been unsuccessfull. How could I achieve this? 

 

Many thanks for your help.

 

Regards.

    Can you share a sample of your data?

      Hi Fowmy , I'm not able to attach a pbix or xlsx file, but, in order to check if this is possible, I'm using a small set of data from CSV, with this content: 

       

      ID;Level;Date
      33;0;26/02/2021
      33;0;31/03/2021
      33;0;23/04/2021
      15;1;30/01/2021
      15;1;26/02/2021
      15;2;31/03/2021
      15;2;23/04/2021
      92;1;26/02/2021
      92;1;31/03/2021
      92;1;23/04/2021

       

      This is my visual:

       

      Where this is my measure Value:

       

      Value =
      VAR __Value = COUNT(Hoja1[ID])
      RETURN
      IF(ISBLANK(__Value),0,__Value)
       
      And this, my desired  output:

       

       

      Hope this is enough 🙂

    Anonymous Not sure why the +0 is not working. You might try something like:

    Value =
  VAR __Value = SUM('Table'[Column])
RETURN
  IF(ISBLANK(__Value),0,__Value)

    Perhaps turn on "show items with no data"?

     

    Not really enough information to go on otherwise, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

    The most important parts are:
    1. Sample data as text, use the table tool in the editing bar
    2. Expected output from sample data
    3. Explanation in words of how to get from 1. to 2.

    Hi! Maybe substitute null values with zeros in the query?

    Isn't it more efficient to do this in M rather than DAX in this case?

    Hi, Anonymous 

    Please try to use the date (or month) from your Dim-Calendar table, not from your fact table.

    I am not sure about how your data model looks like, but try to use Dim-calendar table in X-axis with the same measure, ( adding +0)
