[Highcharts Spline Chart](#) The following example demonstrates a time interval chart. We have already learned about the Highcharts configuration syntax in the previous chapters. Next, let's see how to configure it. * * * ### Example Filename: highcharts_spline_time.htm $(document).ready(function() { var chart = { type: 'spline' }; var title = { text: 'Snow depth at Vikjafjellet, Norway' }; var subtitle = { text: 'Irregular time data in Highcharts JS' }; var xAxis = { type: 'datetime', dateTimeLabelFormats: { // don't display the dummy year month: '%e. %b', year: '%b' }, title: { text: 'Date' } }; var yAxis = { title: { text: 'Snow depth (m)' }, min: 0 }; var tooltip = { headerFormat: '{series.name}
', pointFormat: '{point.x:%e. %b}: {point.y:.2f} m' }; var plotOptions = { spline: { marker: { enabled: true } } }; var series= [{ name: 'Winter 2007-2008', // Define the data points. All series have a dummy year // of 1970/71 in order to be compared on the same x axis. Note // that in JavaScript, months start at 0 for January, 1 for February etc. data: [ [Date.UTC(1970, 9, 27), 0 ], [Date.UTC(1970, 10, 10), 0.6 ], [Date.UTC(1970, 10, 18), 0.7 ], [Date.UTC(1970, 11, 2), 0.8 ], [Date.UTC(1970, 11, 9), 0.6 ], [Date.UTC(1970, 11, 16), 0.6 ], [Date.UTC(1970, 11, 28), 0.67], [Date.UTC(1971, 0, 1), 0.81], [Date.UTC(1971, 0, 8), 0.78], [Date.UTC(1971, 0, 12), 0.98], [Date.UTC(1971, 0, 27), 1.84], [Date.UTC(1971, 1, 10), 1.80], [Date.UTC(1971, 1, 18), 1.80], [Date.UTC(1971, 1, 24), 1.92], [Date.UTC(1971, 2, 4), 2.49], [Date.UTC(1971, 2, 11), 2.79], [Date.UTC(1971, 2, 15), 2.73], [Date.UTC(1971, 2, 25), 2.61], [Date.UTC(1971, 3, 2), 2.76], [Date.UTC(1971, 3, 6), 2.82], [Date.UTC(1971, 3, 13), 2.8 ], [Date.UTC(1971, 4, 3), 2.1 ], [Date.UTC(1971, 4, 26), 1.1 ], [Date.UTC(1971, 5, 9), 0.25], [Date.UTC(1971, 5, 12), 0 ] ] }, { name: 'Winter 2008-2009', data: [ [Date.UTC(1970, 9, 18), 0 ], [Date.UTC(1970, 9, 26), 0.2 ], [Date.UTC(1970, 11, 1), 0.47], [Date.UTC(1970, 11, 11), 0.55], [Date.UTC(1970, 11, 25), 1.38], [Date.UTC(1971, 0, 8), 1.38], [Date.UTC(1971, 0, 15), 1.38], [Date.UTC(1971, 1, 1), 1.38], [Date.UTC(1971, 1, 8), 1.48], [Date.UTC(1971, 1, 21), 1.5 ], [Date.UTC(1971, 2, 12), 1.89], [Date.UTC(1971, 2, 25), 2.0 ], [Date.UTC(1971, 3, 4), 1.94], [Date.UTC(1971, 3, 9), 1.91], [Date.UTC(1971, 3, 13), 1.75], [Date.UTC(1971, 3, 19), 1.6 ], [Date.UTC(1971, 4, 25), 0.6 ], [Date.UTC(1971, 4, 31), 0.35], [Date.UTC(1971, 5, 7), 0 ] ] }, { name: 'Winter 2009-2010', data: [ [Date.UTC(1970, 9, 9), 0 ], [Date.UTC(1970, 9, 14), 0.15], [Date.UTC(1970, 10, 28), 0.35], [Date.UTC(1970, 11, 12), 0.46], [Date.UTC(1971, 0, 1), 0.59], [Date.UTC(1971, 0, 24), 0.58], [Date.UTC(1971, 1, 1), 0.62], [Date.UTC(1971, 1, 7), 0.65], [Date.UTC(1971, 1, 23), 0.77], [Date.UTC(1971, 2, 8), 0.77], [Date.UTC(1971, 2, 14), 0.79], [Date.UTC(1971, 2, 24), 0.86], [Date.UTC(1971, 3, 4), 0.8 ], [Date.UTC(1971, 3, 18), 0.94], [Date.UTC(1971, 3, 24), 0.9 ], [Date.UTC(1971, 4, 16), 0.39], [Date.UTC(1971, 4, 21), 0 ] ] } ]; var json = {}; json.chart = chart; json.title = title; json.subtitle = subtitle; json.tooltip = tooltip; json.xAxis = xAxis; json.yAxis = yAxis; json.series = series; json.plotOptions = plotOptions; $('#container').highcharts(json); }); The output of the above example is: [Highcharts Spline Chart](#)
