Outliers are the values lying beyond the minimum and maximum value of a data point. You can add a scatter series in the chart to show outlier values. Given example shows Box And Whisker Charts with Outliers values. It also contains source code that you can edit in-browser or save to run it locally.
window.onload = function () { var options = { animationEnabled: true, theme: "light2", // "light1", "light2", "dark1", "dark2" title: { text: "Air Quality Index Comparision of Few Popular State" }, subtitles: [{ text: "Based on Number of Days PM2.5 Pollutant Found at Atmosphere in 2016 with County as Sample", fontSize: 15 }], axisY: { title: "Number of Days", tickLength: 0, gridDashType: "dash" }, legend: { cursor: "pointer", itemclick: toggleDataSeries }, data: [{ type: "boxAndWhisker", toolTipContent: "<span style=\"color:#6D78AD\">{label}:</span> <br><b>Upper Extreme:</b> {y[3]},<br><b>Q3:</b> {y[2]},<br><b>Median:</b> {y[4]}<br><b>Q1:</b> {y[1]}<br><b>Lower Extreme:</b> {y[0]}", dataPoints: [ { x: 0, label: "California", y: [-124.25, 46, 159.5, 329.75, 124.5] }, { x: 1, label: "Florida", y: [-226.5, 0, 151, 377.5, 123] }, { x: 2, label: "Indiana", y: [-330, 0, 220, 550, 75.5] }, { x: 3, label: "New York", y: [-191.25, 0, 127.5, 318.75, 55] }, { x: 4, label: "Washington", y: [-20, 211, 365, 596, 346] } ] }, { type: "scatter", name: "Outlier Values", color: "#F15278", markerType: "cross", toolTipContent: "<span style=\"color:#C0504E\">{county}</span>: {y} Days", showInLegend: true, dataPoints: [ { x: 0, label: "California", y: 355, county: "Plumas" }, { x: 3, label: "New York", y: 351, county: "Nassau" } ] }] }; $("#chartContainer").CanvasJSChart(options); function toggleDataSeries(e) { if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) { e.dataSeries.visible = false; } else { e.dataSeries.visible = true; } e.chart.render(); } }
You can add as many outlier series as required, by adding additional scatter series in the data array. The markers can be customized using markerType & markerColor properties. Other related customizations are markerSize, markerBorderColor etc.
