Clarification per discussion with Jaime: this is related to the data that was compiled for the Equity Landscape Dashboard, but is not actually intended for the Dashboard. Instead, it's responding to the fact that we keep querying the same regional views for quarterly learning discussions, staff meetings, etc.

@HXi-WMF updates to charts per our discussion:

  • separate chart files into two groups: Readers (unique devices, content interactions) and Editors (active editors, active editors - returning vs new, net new content). This will make it easier to incorporate the charts into the two separate repos we have right now.
  • add buffer/padding to Y axis, so that the chart's peak and trough do not extend through the full Y axis (per the draft Data visualization guidelines that Maya mentioned: "a good measure is for the line to fill two-thirds of the chart area height"
  • For the data loss data: I agree with your suggestion of putting the data directly into the code as a temporary solution, rather than referencing data from Google docs. Make sure it’s well-commented.

@Volker_E After discussing this with the team, I suggest coming in to office hours to help you get the data needed from Superset. I explored the data and put together this dashboard - https://superset.wikimedia.org/superset/dashboard/403/ - so perhaps that meets your needs? The first chart shows the proportion of pageviews from IE11 out of all pageviews - and has conditional formatting to flag where that proportion is above 0.1%
