Define the Header

The title of the chart can be defined using the header array where the following options can be set: visible, style, textStyle, compass, orientation.

To define the header’s text color and size, use the following code:

header: {
               text: "Hardware Distribution",
               textStyle:{
                    fill:"#6699cc",
                    stroke: "#6699cc",
                    "font-size": "24pt",
                    }
          
    },
