GWT Highcharts - Area Chart using Spline
We have already seen the configurations used to draw a chart in Highcharts Configuration Syntax chapter. Now, let us see an example of a Area Chart using spline. We will also understand additional configuration. We have changed the type attribute in chart.
chart
Configure the chart type to be 'areaspline' based. chart.type decides the series type for the chart. Here, the default value is "line".
chart.setType(Type.AREA_SPLINE);
Example
