Angular Highcharts - Stacked Area Chart

Following is an example of a stacked Area Chart.

We have already seen the configurations used to draw a chart in Highcharts Configuration Syntax chapter. Now, let us see an example of a stacked Area Chart.

plotOptions

The plotOptions is a wrapper object for configuration objects for each series type. The configuration objects can be overridden for each series item as given in the series array. This is to stack the values of each series on top of each other.

Configure the stacking of the chart using plotOptions.area.stacking as "normal". Possible values are null which disable stacking, "normal" stacks by value and "percent" stacks the chart by percentages.

var plotOptions = {
   area: {
      stacking: 'normal',
      lineColor: '#666666',
      lineWidth: 1,
      marker: {
         lineWidth: 1,
         lineColor: '#666666'
      }
   }
};
