highcharts: disable only a single element in legend so it cannot be clicked
I was wondering is it possible to prevent only a one element in plot le开发者_运维技巧gend from disabling/enabling. Let's say I have three categories in my legend: 'car1', 'car2', 'car3'. I would like to show/hide only 'car2' and 'car3', while 'car1' is shown all the time.
Thank you!
If it's always a certain series that you want to disable show/hide, then within the legendItemClick return false for that series.
For example:
plotOptions: {
series: {
events: {
legendItemClick: function(event) {
return !(this.name == 'car1');
}
}
}
},
