adding functionality to the default legend onClick function

[CodeMazeSolver]

@giovanniciriello you don't need to override, you can call it directly

'legend' : {
    onClick: function (evt, item) {
        // do something
        Chart.defaults.global.legend.onClick.call(this, evt, item)
     },
    display: true,
    labels: ...

I suppose it's now (version 3.6.2) called:

Chart.defaults.plugin.legend.onClick.call(this, evt, item)

However, I then get the following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'chart')

Using chrome dev tools this is the line in chart.js causing troubles:

Legend onClick, onHover, and onLeave options now receive the legend as the 3rd argument in addition to implicitly via this

  options: {
    plugins: {
      legend: {
        onClick(evt, item) {
          Chart.defaults.plugins.legend.onClick.call(this, evt, item, this);
          // or Chart.defaults.plugins.legend.onClick(evt, item, this);
        }
      }
    }
  }
