How do you change the colour of each category within a highcharts column chart?

Question

I have have a column chart which has a number of categories, each with a single data point (e.g. like this one). Is it possible to change the colour of the bar for each category? i.e. so each bar would have its own unique colour rather than all being blue?

Answer 1

Also you can set option:

  {plotOptions: {column: {colorByPoint: true}}} 

for more information read docs

Answer 2

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
