Can't change dateFormat

[leongaban]

Here is a function that explicitly changes the dateFormat on the chart object before it gets the downloadCSV method called on it.

Next in the first screenshot, you can see that this.options.exporting has the new dateFormat I added.

However by line 48 options.dateFormat is still undefined so then it always defaults to '%Y-%m-%d %H:%M:%S'

this.downloadCsv = () => {
        const chart = ChartExport.getChart();
        chart.options.exporting.filename = createFileName(chart);
        chart.options.exporting.dateFormat = '%H:%M:%S';
        console.log('chart', chart)
        chart.downloadCSV();
        this.$close();
    };

Love the plugin btw! Just working out the final kinks in formatting the CSV.

Not a bug, needed to set the dateFormat on a new csv key for exporting

exporting.csv.dateFormat Which date format to use for exported dates on a datetime X axis. See Highcharts.dateFormat.

exporting: {
    allowHTML: true,
    enabled: false,
    sourceWidth: 640,
    sourceHeight: 400,
    csv: {
        dateFormat: '%Y-%m-%d'
    },
    chartOptions: {
        title: {
            text: null
        }
    }
},
