I am trying to create Box plot in tableau using calculated fields, but the values from show me and calculations are not matching.

Hello All,

I am trying to create Box plot in tableau using calculated fields.

Upper Whisker(Q3 + 1.5×IQR)

Upper Quartile-Q3

Median

Lower Quartile-Q1

Lower Whisker(Q1 – 1.5×IQR )

Can anyone help me to create box plot using these calculated fields.

When I create Box plot using tableau 'Show Me' tool,It is giving incorrect Upper and lower whisker values,

However I want values based on Upper Whisker(Q3 + 1.5×IQR) and Lower Whisker(Q1 – 1.5×IQR )

I have attached sample workbook.

Please help me to correct Upper and lower whisker values in tableau default box plot or let me know how to update in Box plot using field I created, so the values are correct.
