Column with rotated labels

Following is an example of a Column Chart with Rotated Labels.

We have already seen the configuration used to draw a chart in Highcharts Configuration Syntax chapter. Let us now see additional configurations and also how we have added rotation attribute in dataLabels.

An example of a Column Chart with rotated labels is given below.

dataLabels

dataLabels is a wrapper object to handle data labels within charts.

Text rotation in degrees. Note that due to a more complex structure, backgrounds, borders and padding will be lost on a rotated data label. This defaults to 0.

dataLabels = {
   enabled: true,
   rotation: -90,
   color: '#FFFFFF',
   align: 'right',
   format: '{point.y:.1f}', // one decimal
   y: 10, // 10 pixels down from the top
   style: {
      fontSize: '13px',
      fontFamily: 'Verdana, sans-serif'
   }
}
