In the Tableau course you keep talking about 2017 and 2016 years, but you only gave an excel document with 2016 so technically all of these videos are wrong. The students are unable to do the exercises with the video because you uploaded the wrong excel file. So all of the examples and things we are supposed to be doing with the video we are unable to do because the tesla excel file only has 1-year of data not 2 years of data.
Thanks for reaching out!
Apologies for the confusion.
The Excel file, which is provided contains both 2016 and 2017. You can check that if you filter or if you create a pivot table in Excel. When you add the data in Tableau, you should also see the two years.
