Customize the border width and color of a specific column in HighCharts based on dynamic data

I am looking to dynamically change the border width and color of only one column in a basic column chart. Here is an example: 

var chartingOptions = {
chart: {
    renderTo: 'container',
    type: 'column'
},
xAxis: {
    categories: ['5:1', '4:1', '3:1', '2:1', '1:1', '1:2', '1:3', '1:4', '1:5']
},
plotOptions: {
    column: {           
      grouping: false
    }
},
series: [
    {
    name: 'Serie 2',
    data: [20, 24, 30, 40, 60, 80, 90, 96, 100]},
{
    name: 'Serie 1',
    data: [100, 96, 90, 80, 60, 40, 30, 24, 20]}
            ]
};

var chart = new Highcharts.Chart(chartingOptions);

Check out JSFIDDLE here.

I attempted to modify it directly for the first series by using:

chart.series[0].data[2].series.borderColor = 'black'

However, the series did not update. Any suggestions would be appreciated!

Answer №1

To modify the SVG element, you must adjust the properties for stroke and stroke-width.

For instance, check out this example: http://jsfiddle.net/abc123xyz/4/

Answer №2

To change the color of a column in a chart, use <code>chart.series[0].data[2].series.color = 'black'
. Please note that this will also affect the color of the tooltip.

If you want to explicitly set the color of individual columns, you can do so like this:

data: [{
    name: 'Point 1',
    color: '#00FF00',
    y: 0
}, {
    name: 'Point 2',
    color: '#FF00FF',
    y: 5
}]

For more information, visit this link.

You can also check out this [fiddle] here.

Answer №3

The borderColor and borderWidth options are specific to series objects and cannot be used with data objects. For more details on this, please refer to the documentation provided in the link above.

If needed, you can manually add borderColor and borderWidth properties to data objects by editing the source code of highcharts.js.

I hope this information is useful to you.
