flot pie chart tooltip percentage

Question

I have having a problem with flot pie chart, its not showing correct percent value in tooltip, for example it shows series1:%p.0%

js code

  var data = [{
    label: "Series 0",
    data: 1
}, {
    label: "Series 1",
    data: 3
}, {
    label: "Series 2",
    data: 9
}, {
    label: "Series 3",
    data: 20
}];
var plotObj = $.plot($("#flot-pie-chart"), data, {
    series: {
        pie: {
            show: true
        }
    },
    grid: {
        hoverable: true
    },
    colors: ["#99c7ce","#efb3e6","#a48ad4","#AEC785","#fdd752"],
    tooltip: true,
    tooltipOpts: {
        content: "%p.0%, %s", // show percentages, rounding to 2 decimal places
        shifts: {
            x: 20,
            y: 0
        },
        defaultTheme: false
    }
});

Please help to resolve this.

thanks

You Need to include jquery.flot.tooltip.min.js and change few setting as per below working example to display the tooltip with value.

 datapie = [ {label: "Running", data: 19.5, color: '#e1ab0b'}, {label: "Stopped", data: 4.5, color: '#fe0000'}, {label: "Terminated", data: 36.6, color: '#93b40f'} ]; function legendFormatter(label, series) { return '<div ' + 'style="font-size:8pt;text-align:center;padding:2px;">' + label + ' ' + Math.round(series.percent)+'%</div>'; }; $.plot($("#placeholder"), datapie, { series: { pie: {show: true, threshold: 0.1, // label: {show: true} } }, grid: { hoverable: true }, tooltip: true, tooltipOpts: { cssClass: "flotTip", content: "%p.0%, %s", shifts: { x: 20, y: 0 }, defaultTheme: false }, legend: {show: true, labelFormatter: legendFormatter} }); 

 #flotTip { padding: 3px 5px; background-color: #000; z-index: 100; color: #fff; opacity: .80; filter: alpha(opacity=85); }
