export csv from highcharts

Question

I'm using angular-5,angular2-highcharts version 0.5.5 and highcharts version 6.0.7.

I want to add in my html in not in the chart a button for download the chart in png or csv.

Png one works fine, but I can't got it with csv:

This is my code:

downloadPng(): void {   //this one works
   this.chart.exportChart({
      type: 'image/png',
      filename: this.title
    });
}

downloadCsv(): void {   //this one crashes
   this.chart.exportChart({
      type: 'text/csv',
      filename: this.title
    },{
      itemDelimiter: ';',
      csv: this.chart.getCSV() 
    });
}

When crashes it redirects to

https://export.highcharts.com/

with this text

unexpected return from chart generation - please check your input data

I think I need to do something else for csv export. Can anybody help me?

Answer 1

You need the export-data module. It extends a chart with downloadCSV method.

function downlaodCsv() {
  chart.downloadCSV()
}
