Incorrect version information in package download graph

[mstimberg]

I'm one of the developers of the "brian" package: https://crate.io/packages/brian/

The graph on our package page shows the expected peak in downloads after our release two weeks ago. The colors/tooltips in the graph seem to be off, though: According this graph, all versions of our package have been equally downloaded last week (leaving only about a 10th for downloads of the most recent version). The text stating the total number of downloads for the most recent version seems to be correct, on the other hand, attributing all the downloads in the last week to the most recent version.

I'm not sure whether this is a display issue or the data is fetched incorrectly.
