Multiple Graphs on a Chart

Generally, to add an additional graph to a chart you should use the addSeries method.

As a parameter, the method takes an object of the graph you'd like to add to the chart. The graph is specified in a standard way.

Single graph

var barChart =  new dhtmlXChart({
    view:"bar",
    container:"chartBox",
    value:"#sales#",
    color: "#58dccd",
    xAxis:{ template:"'#year#" }
});

Multiple graphs

var barChart =  new dhtmlXChart({..});
 
barChart.addSeries({
     view: "line",
     item:{  radius:0 },
     line:{  color:"#36abee" },
     value:"#sales3#"
});

If you add to the chart a graph of the same type, you can omit the view attribute:
