[Highcharts Spline Chart](#)
The following example demonstrates a spline chart with symbols.
We have already learned about Highcharts configuration syntax in previous chapters. Next, let's see how to configure it.

## Configuration
We use the `marker.symbol` property to configure the symbol. The symbol can be 'square', 'diamond', or an image URL. Symbols can be added to any data point:
var series= [{ name: 'Tokyo', marker: { symbol: 'square' }, data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, { y: 26.5, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' } }, 23.3, 18.3, 13.9, 9.6] }, { name: 'London', marker: { symbol: 'diamond' }, data: [{ y: 3.9, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)' } }, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8] }];
### Example
Filename: highcharts_spline_symbols.htm
$(document).ready(function() { var chart = { type: 'spline' }; var title = { text: 'Monthly Average Temperature' }; var subtitle = { text: 'Source: WorldClimate.com' }; var xAxis = { categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'] }; var yAxis = { title: { text: 'Temperature' }, labels: { formatter: function () { return this.value + 'xB0'; } }, lineWidth: 2 }; var tooltip = { crosshairs: true, shared: true }; var plotOptions = { spline: { marker: { radius: 4, lineColor: '#666666', lineWidth: 1 } } }; var series= [{ name: 'Tokyo', marker: { symbol: 'square' }, data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, { y: 26.5, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' } }, 23.3, 18.3, 13.9, 9.6] }, { name: 'London', marker: { symbol: 'diamond' }, data: [{ y: 3.9, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)' } }, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8] } ]; 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:
