The application of stacked-to-grouped barchart technique example from here, applied to display age-ranges data of population of some provinces in Indonesia.
Hint : at first glance, this my looks like an ordinary bar chart, however, this is actually a stacked bar chart in a sneaky disguise! Just choose the ‘Gender’ option to see how it means….
Hover on bars see tooltip. Play with the the controls to choose province to view, to choose bars view by total (the ‘All’ option), or by gender (the ‘Gender’ option). While the ‘Gender’ option is active, you can use click on the ‘Male’ or ‘Female’ legend rectangle on the right to plot/choose a single gender. Use the ‘Sort’ checkbox to sort bars.
