Can you please check at the age and gender summary page, it does not have the scroll bar to view the next page. Here i attached the screen shot for your reference, as you can see, we can only view the summary page to grade 10, while the grade 11 and 12 are hiding as it does not fit in the page. If you can add a scroll bar to right and left view that would be great. Thanks!
Sure, an simple fix would be to add overflow-x: scroll` to the #content-wide div in the theme main.css file. It would catch this and any other overflowing charts.
When I get through the triage for my current to-do list I hope to add the fancier double-scroll and pinned first-column code to the general theme js/css files so we can use it more universally
