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 seriesType property. Series property is to be useed to specify properties of each series individually. We've already seen the configuration used to draw this chart in Google Charts Configuration Syntax chapter. So, let's see the complete example.

//combination chart var chart = new google.visualization.ComboChart(document.getElementById('container'));
