The plot obtained in the exercise does not show the median ( black line) for ‘MO Sold’
The reason the line isn’t showing is because both the Mode and the Median of this vector have the same value —since the Mode is calculated (and plotted) before the Median, the line associated with it takes precedence. While we don’t ask for it in this mission, the best solution would be to adjust the opacity/transparency for each line so that lines underneath them are visible as well.
How a new learner would know this. This must be clarified after the exercise .
Agreed! We have logged this issue. Thanks for bringing this up.
