Hiding dataset shows incorrect axis

[AcuarioCat]

On charts with multiple datasets clicking one dataset to hide it has odd behavior.

This can be seen on https://www.chartjs.org/samples/latest/charts/line/multi-axis.html, clicking one of the datasets to disable it replaces the axis scale with values from -1 to 1.

Expected behavior:
Either leave the axis unchanged or hide the axis.

Either leave the axis unchanged ...

To keep the axis unchanged, you need to set explicit min/max on the axis, else the scale limits are automatically adjusted to the "visible" data or fallback to [-1:1] if nothing is visible.

... or hide the axis.

This feature has been implemented in #5885 and will be released in 2.8.0. However, you will have to explicitly configure the axis display option to 'auto'.
