In Cuba Platform 6.5, how do you use the Chart Legend Listeners?

I was able to successfully get a PieChart Listener to function as described in the release notes
at (CUBA Platform and Studio Release Notes), but I’m struggling to get the Legend listeners to work.

I’m using these imports


import com.haulmont.charts.gui.components.charts.Chart;
import com.haulmont.charts.gui.components.charts.PieChart;

calling the code below:

private void updateCharts() {
    //Pie Chart
    pieChartsDs.clear();
    List<PieChartValues> pieChartList = applicationService.findArrayApplicationStatusCounts(null);
    for (PieChartValues pieChartValues : pieChartList) {
        pieChartsDs.includeItem(pieChartValues);
    }
    PieChart pieChart = (PieChart) chartPie;
    pieChart.setColors(TabColors.getColors());
    pieChart.setLabelsEnabled(true);
}

And the code for the event listeners are displayed in the attached file.

Hi,

Use getDataItem() or getEntity() method with Legend events:


pieChart.addLegendMarkerClickListener(event -> {
    PieChartValues item = (PieChartValues) event.getEntityNN();
});

See com.haulmont.charts.gui.components.charts.Chart.LegendItemEvent for details.

You can see all the available options from your IDE in auto completion popup (see attachment).
