[V5] The pane supports collapse and restore.

[1123612483]

Is your feature request related to a problem? Please describe.

Here is a use case: when all the series of a particular pane are hidden, the pane should be collapsed; otherwise, the pane should be restored.

const secondPane = chart.pane()[1];
const series = secondPane.getSeries();
const visible = series.some(s => s.option().visible);

secondPane.setHeight(visible ? 200 : 0); // It doesn't work when visible is set to false because the minimum height of the pane is 30px.

Describe the solution you'd like
Based on this use case, the IPaneApi needs to add two methods: collapse() and restore().

const secondPane = chart.pane()[1];
const series = secondPane.getSeries();
const visible = series.some(s => s.option().visible);

if (visible) {
   secondPane.restore();
}else {
   secondPane.collapse();
}
