Export data methods not found on chart reference

[mtinnes]

Is it possible to call the exporting methods (ie: toCSV()) from the chart reference? I'm capturing the instance using the callback method on the highchartsChart directive, however there is no toCSV() method available. I'm importing the export libraries and can perform the export via the chart hamburger menu, but not from code.

Relevant code is as follows:

<div highchartsChart
     [options]="chartOptions"
     (chartInstance)="chartInstance($event)"></div>

chartInstance(chart: Highcharts.Chart) {
    console.log(chart.toCSV());
}

provideHighcharts({
    modules: () => {
        return [
            import('highcharts/esm/modules/exporting'),
            import('highcharts/esm/modules/export-data'),
            import('highcharts/esm/modules/map'),
        ]
    }
})

Using:

"@angular/core": "^20.3.0",
"highcharts": "^12.4.0",
"highcharts-angular": "5.1.0",

Hi @mtinnes, thanks for the report. You're right — the toCSV() function isn’t defined in the TypeScript definitions. It can be added.

Turns out the issue was I need to call 'getCSV()', not 'toCSV()'. So the exporting works on the instance provided from chartInstance(), just no typing currently.
