Metrics graphs glitches
It seems that some graphs in metrics.tpo have display glitches.
Examples:
https://metrics.torproject.org/users.html?graph=direct-users&start=2012-03-14&end=2012-06-04&country=sy&events=on&dpi=72#direct-users (the last one is related to the censorship events upscores/downscores graphs)
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
