[Solved]-Removing highcharts.com credits link-Highcharts

credits : null

also works to disable the credits

Add this to your css.

.highcharts-credits {
display: none !important;
}

Both of the following code will work fine for removing highchart.com from the chart:-

credits: false

or

credits:{
 enabled:false,
}

add

credits: {
    enabled: false
}

[NOTE] that it is in the same line with xAxis: {} and yAxis: {}

It's said here that you should be able to add the following to your chart config:

  credits: {
    enabled: false
  },

that will remove the "Highcharts.com" text from the bottom of the chart.

You can customise the credits, changing the URL, text, Position etc. All the info is documented here: http://api.highcharts.com/highcharts/credits. To simply disable them altogether, use:

credits: {
    enabled: false
},
