I have faced a problem that one line in graph has strange visualization.
Graph collects data from 3x different data sources (with influx 1.4.2) with interval 1m
And every 5 min there is gap.
You can visualize it by changing the time interval from visualization style set time interval 1. Second thing just zoom that specific time which you want to see.
Is the raw data into the db once a minute? If so are all the samples present and exactly on 1 minute intervals? Show us some of the raw data from the db around the glitches.
