Edge values with InfluxDB

I was testing out InfluxDB to replicate some of our dashboards in a more long term storage environment. Data comes from Prometheus, however I can’t get the edge values right.

Here’s an example with Prometheus data

And here is the same data from InfluxDB

Looks like I get zeroes around the edges, which screw up the axes.

What’s going on and how do I mitigate this?
