Opgave
Swipe to start coding
You are going to work with nearly the same code as in the previous task. You just need to modify certain things:
- Group the values of the
dfDataFrame by'Store', and then'Holiday_Flag'column (the order is important). Then, after selecting the'Weekly_Sales'column, compute the mean values. - Within the
.barplot()function, set the parameter, so that there will be separate bars for each of the unique values of the'Holiday_Flag'column.
