Show discrete, numerical comparisons across categories by creating a bar chart with bar heights proportional to the values in a numeric column.
Details
Create a bar chart by selecting a categorical variable (X) and a numerical variable (Y). The Y numerical variable can be calculated manually before, or passed and handled automatically by the module. Add a categorical fill variable in order or colour and segment your bars.
