Highcharts - Configuration Syntax

In this chapter, we will showcase the configuration required to draw a chart using the Highcharts API.
Create an HTML page with the jQuery and Highcharts javascript libraries.

Here the container div is used to contain the chart drawn using Highcharts library.
Highcharts library uses very simple configurations using json syntax.
$('#container').highcharts(json);

Here json represents the json data and configuration which the Highcharts library uses to draw a chart within the container div using the highcharts() method. Now, we will configure the various parameters to create the required json string.
Configure the title of the chart.
var title = {
   text: 'Monthly Average Temperature'   
};
Configure the subtitle of the chart.
var subtitle = {
   text: 'Source: WorldClimate.com'
};
Configure the ticker to be displayed on the X-Axis.
var xAxis = {
   categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun'
      ,'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
};
Configure the title, plot lines to be displayed on the Y-Axis.
var yAxis = {
   title: {
      text: 'Temperature (\xB0C)'
   },
   plotLines: [{
      value: 0,
      width: 1,
      color: '#808080'
   }]
};  
Configure the tooltip. Put suffix to be added after value (y-axis).
var tooltip = {
   valueSuffix: '\xB0C'
}
Configure the legend to be displayed on the right side of the chart along with other properties.
var legend = {
   layout: 'vertical',
   align: 'right',
   verticalAlign: 'middle',
   borderWidth: 0
};
Configure the data to be displayed on the chart. Series is an array where each element of this array represents a single line on the chart.
var series = [
   {
      name: 'Tokyo',
      data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
   }, 
   {
      name: 'New York',
      data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
   }, 
   {
      name: 'Berlin',
      data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
   }, 
   {
      name: 'London',
      data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
   }
];
Combine all the configurations.
var json = {};

json.title = title;
json.subtitle = subtitle;
json.xAxis = xAxis;
json.yAxis = yAxis;
json.tooltip = tooltip;
json.legend = legend;
json.series = series;
$('#container').highcharts(json);
