Hello, there is an error in this graph triggering around 142 errors. I know little about how this graph works, but it seems to relate to one of the formulaes. User:TheDJ any idea what's happening here and do you know how to fix it? Jdlrobson (talk) 00:35, 11 March 2021 (UTC)

 * I can replicate this in Firefox by dragging the timeline at the bottom of the graph in Landline. I've poked at the sandbox but without much luck. User:Milimetric (WMF), User:Jseddon (WMF) any idea what's going wrong here? Screenshot of bug with global heat maps template.png Jon (WMF) (talk) 16:56, 26 March 2021 (UTC)
