Steps to replicate the issue (include links if applicable):
- View the impact module's "Views on articles you've edited" graph
What happens?:
The graph seems to be broken, at least for some users:
What should have happened instead?:
Graph should display a more cumulative pageview sparkline, as outline in design requirements.
Software version (skip for WMF-hosted wikis like Wikipedia):
Other information I can replicate on enwiki and test wiki. I can replicate on Chrome and Safari.
For certain other users, the Impact module was empty, with the following error in console:
TypeError: Cannot convert undefined or null to object at Function.assign (<anonymous>) at useUserImpact.js:67:18 at Array.map (<anonymous>) at quantizeViews
