Not a fix, but a relief, is to use ```dataZoom: [{ textStyle: { width:77, overflow: 'break' } }]```

two gauges on top of each other usually solves similar problems - see #19971

@alex-anderson-addepar - sure, adding a new feature is better. It just takes a lot of knowledge to build, and lot of time to be approved. So I focus on workarounds.

not-a-bug Yes, it's hard to look at a **44K points** chart without _dataZoom_. But improvements can be made: ``` const data = ... 44K points with plenty of 0 and...
