Incorrect bar chart display

For some of my bar charts, bars with larger values are smaller than bars with smaller values - see attached screenshot. Not quite sure how to reproduce this as other bars in the same chart are displayed correctly.

I can try to invest some time to reproduce this with a toy example but I'd like to get some feedback first whether this is a known issue.

Hi @anselm
You are using split Y-axis. Disable that in visualization Settings > Axes.

aha! thank you very much
