Continuous axis is not possible in a box plot, it must be categorical which means 'Line from Column Values' is not possible. In order to extend the functionality of box plot to be able to join same set of reference points together for all the box plots available on the visualization, can we allow changing of x-Axis' mode to continuous.
you can put a horizontal line from table to fix the issue
this is critical to use boxplot, can you help on it?
