Subscription Workers graph displays non-chronologically?

[mjvotaw]

I'm not really sure where to raise this issue, since I think it's part of Hasura Cloud, but, I recently realized that the "Average execution time over time" graph doesn't seem to display data in chronological order, compared to the other two graphs. I've tested this in Firefox and Chrome. The problem only seems to appear if I select "Last 12 hours" for the time range, and it only seems to affect the "Average execution time over time" graph.
