Getting default pane / first created pane out of multiple panes

[vishnuc]

Hello initially this is the default pane , chart.panes()[0] but after doing swapPanes and moveTo panes with multiple panes.. is there a way to find out which is the original default pane... is there a default way to do it ?

Because its tedious process to keep reference after swapPanes and moveTo .... or can we assign a id to it so we can later do chart.getPane(id) something like this ?

You are given an instance of IPaneApi when using chart.panes()[0]. You can consider this the 'default' pane and keep a reference to it. You can use the paneIndex() method to get it's current index on the chart.

const first = chart.panes()[0];

chart.swapPanes(0, 1);

console.log(first.paneIndex()); // -> 1
console.log(chart.panes().indexOf(first)); // -> 1

chart.swapPanes(0, 1);

console.log(chart.panes().indexOf(first)); // -> 0
console.log(first.paneIndex()); // -> 0
