Dual Axes, Line and Column

Following is an example of a chart with Dual Axes, Line and Column.

We have already seen the configuration used to draw a chart in Highcharts Configuration Syntax chapter.

An example of a combination chart having Dual Axes, Line and Column is given below.

Configurations

Let us now see the additional configurations/steps taken.

YAxis

Get multiple yAxis using chart.getYAxis(index) method.

chart.getYAxis(0);  
chart.getYAxis(1);
