A combination chart helps in rendering each series as a different marker type from the following list: line, area, bars, candlesticks, and stepped area. To assign a default marker type for series, use the series type property. Series property is to be used to specify properties of each series individually. We’ve already seen the configuration used to draw this chart in the Google Charts Configuration Syntax chapter. So, let’s see the complete example.
Configurations
We’ve used ComboChart class to show the combination-based chart.
//combination chart
var chart = new google.visualization.ComboChart(document.getElementById('container'));
