Clickable Pie Segments

[Tim Hill]

Hi there,

Pretty new to highcharts (GWT flavour) and I have an issue with pie charts. What I would like to be able to do is to display a pie chart that allows the use to click on a segment and drill down into the data and display another pie chart with more focused data, dependent on which segment of the original pie was clicked. I have been able to implement this using a line chart (PointClickEvent), but the only relevant event for a pie chart (that I can see) is PointLegendItemClickEvent, which doesn't appear to do anything when added to a series.

Is what I am aiming to do possible with a pie chart? If so, any pointers?!

Thanks in advance.

Tim

Hi Tim,

For pie charts, I use this:

1 2 3 4 5 6 7 8

chart.setSeriesPlotOptions(new SeriesPlotOptions() .setPointClickEventHandler(new PointClickEventHandler() { @Override public boolean onClick(PointClickEvent evt) { Point point = evt.getPoint(); //... }) );
