    Tableau is showing extra value that doesn't exist in data

      Hello everyone!
      This is my first question here, and I'm kind of new to Tableau, so please bear with me if my question is not clear.

      I have a set of data, which I have to do some manipulation on it, then save it again.

      For the purpose of check, I am not doing any manipulations in my first version, so the process is going as following:

      original_data.csv ---> manipulation through python script ---> new_data.csv

      Then, I am comparing the visualization of the new_data to the original_data,

      here is what I get.

       

      original_data

      original.png

      new_data

      new.png

      as you may notice, there are strange vertical lines out there, even that I don't have values in my data like that.

      Do you have any idea why this is happening? How could be fixed?

       

      Thank you
