Additional data on each DataSeriesItem

Hi, I can`t find a way to set additional data on a DataSeriesItem for use when calling

In the underlying highcharts this is possible using the technique described here:

How can I do this in VaadinCharts?


Just extend DataSeriesItem and add some property. Then you can access it with {point.myProperty} or whatever you name it.

    public static class MyDataSeriesItem extends DataSeriesItem {
        private String myProperty;

        public MyDataSeriesItem(Date yearDate, Number temp, String myMeta) {
            super(yearDate, temp);
            this.myProperty = myMeta;

        public String getMyProperty() {
            return myProperty;

        public void setMyProperty(String myMeta) {
            this.myProperty = myMeta;
