How do you change the colour of each category within a highcharts column chart?
Solution 1:
You can also set the color individually for each point/bar if you change the data array to be configuration objects instead of numbers.
data: [
{y: 34.4, color: 'red'}, // this point is red
21.8, // default blue
{y: 20.1, color: '#aaff99'}, // this will be greenish
20] // default blue
Example on jsfiddle
Solution 2:
Also you can set option:
{plotOptions: {column: {colorByPoint: true}}}
