Description

I have a candle stick chart, with temporal series, I use type: "time". During pan, after a number of move of the mouse, the pan jump or move continuously on the same side even if I move the pointer on the other direction.

I have tried lot of thing, the issue disappear if I use a "linear" type for x but in that case I have not the desired tick and formatting.

I have set limits on x correctly.

It seems worst when streaming data but it could occurs even when there is not data update.

The time type seems to modify something that interact in the wrong way during a pan.

Research direction

Start by reproducing the reported candle stick chart with a time-based x axis, panning repeatedly in both directions and comparing it with a linear axis. Check whether streaming updates are required; done means panning remains stable in both directions with time ticks and formatting preserved.
