Charts - how to listen to series selection

Flow
1

Hi all,

Is there a way to know when the user selects/clicks on a Series of a Pie Chart for instance?

The below doesn’t seem to help.


        chart.addChartSelectionListener(new ChartSelectionListener() {
            public void onSelection(ChartSelectionEvent e) {
                System.out.println(e.getComponent() + " " + e.getValueStart() + " " + e.getValueEnd() + " " + e.getSelectionEnd());
            }
        });
        chart.addLegendItemClickListener(new LegendItemClickListener() {
            public void onClick(LegendItemClickEvent e) {
                System.out.println(e.getSource() + " " + e.getSeries());
            }
        });
        chart.addChartClickListener(new ChartClickListener() {
            public void onClick(ChartClickEvent e) {
                System.out.println(e.getxAxisValue() + " " + e.getyAxisValue());
            }
        });

Hi,

Use point click listener. Slices are data points in pie chart.

Hi,

You are missing GSON library. With sane dependency management system like Maven you should get it automatically. Else you can copy it from the zip packages lib directory or download it from gson site.
