Developer Stats graph data disappears when you toggle legend items


When enabling/disabling legend items on any of the Developer Stats graphs, the last data point on that graph will vanish. The page needs to be reloaded to view the full data again, and it is impossible to view a filtered view of the full data currently because of this bug (you always lose a data point when toggling items).

How to reproduce

  • Go to the Developer Stats of any place
  • Scroll down to the graphs
  • Spam enable/disable on any of the legend checkboxes on the side
  • Watch as last data point vanishes on each click until none are left

This occurs with all extensions disabled.


Can confirm I also experience this, but just to note that I only experience this under the hourly data, not daily nor monthly.
