Visualforce does not appear to expose any mechanism for onclick, but does have a tooltip extension mechanism that might meet your needs (though it is undocumented).

Here a couple of extra fields called other1 and other2 are added to the data:

public class PieChartController {
    public List<PieWedgeData> getPieData() {
        List<PieWedgeData> data = new List<PieWedgeData>();
        data.add(new PieWedgeData('Jan', 30));
        data.add(new PieWedgeData('Feb', 15));
        data.add(new PieWedgeData('Mar', 10));
        data.add(new PieWedgeData('Apr', 20));
        data.add(new PieWedgeData('May', 20));
        data.add(new PieWedgeData('Jun', 5));
        return data;
    public class PieWedgeData {
        public String name { get; set; }
        public Integer data { get; set; }
        public String other1 { get; set; }
        public String other2 { get; set; }
        public PieWedgeData(String name, Integer data) {
            this.name = name;
            this.data = data;
            this.other1 = String.valueOf(Math.random());
            this.other2 = String.valueOf(Math.random() * 1000);

and rendered in the tooltip using this:

<apex:page controller="PieChartController" title="Pie Chart">
    <apex:chart height="350" width="450" data="{!pieData}">
        <apex:pieSeries dataField="data" labelField="name">
            <apex:chartTips height="75" width="200" rendererFn="renderChartTip"/>
        <apex:legend position="right"/>
function renderChartTip(klass, item) {
    var m = item.storeItem;
            + '<table>'
            + '<tr><td><b>Data</b>&nbsp;</td><td>' + m.get('data') + '</td></tr>'
            + '<tr><td><b>Other 1</b>&nbsp;</td><td>' + m.get('other1') + '</td></tr>'
            + '<tr><td><b>Other 2</b>&nbsp;</td><td>' + m.get('other2') + '</td></tr>'
            + '</table>'

for this result on-mouseover rather than on-click:
