No longer able to toggle between normal and isometric charts

With the introduction of the Profile activity overview feature from GitHub, I am no longer getting the toggle button to switch between the normal and isometric charts.

Same here, the feature also kind of breaks the layout and the Hide normal chart button no longer does anything.

Thanks for the report. I'll get this fixed up soon.
