I need to hide other series in a HighChart(Line chart) when clicking a legend, So I have tried something that currently hiding other series lines, but when I try to click the same legend it showing the other series again, which is not correct.
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line',
marginRight: 130,
marginBottom: 25
},
plotOptions: {
line: {
events: {
legendItemClick: function () {
chart.yAxis[0].addPlotLine({
value : 7.5,
color : 'green',
dashStyle : 'shortdash',
width : 2,
label : {
text : 'My PlotLine'
}
});
if (!this.visible)
return true;
var seriesIndex = this.index;
var series = this.chart.series;
for (var i = 0; i < series.length; i++)
{
if (series[i].index != seriesIndex)
{
series[i].visible ? series[i].hide() : series[i].show();
}
}
return false;
//return false; // <== returning false will cancel the default action
}
}
,
showInLegend: true
}
},
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
this.x +': '+ this.y +'°C';
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]

}]
});
});
});
in simple words, when I click a legend it should only open concern line only,

Reset to default 6You can solve it to your specification like this:
var seriesIndex = this.index;
var series = this.chart.series;
if (this.visible && this.chart.restIsHidden) {
for (var i = 0; i < series.length; i++) {
if (series[i].index != seriesIndex) {
series[i].show();
}
}
this.chart.restIsHidden = false;
} else {
for (var i = 0; i < series.length; i++) {
if (series[i].index != seriesIndex) {
series[i].hide();
}
}
this.show()
this.chart.restIsHidden = true;
}
return false;
This checks if the item clicked is visible and the rest are hidden, if it is then it should show all. Otherwise it should hide all but the clicked item. I used a custom bool value to track if the rest is hidden or not.

Better solution for large no of Legends
plotOptions: {
line: {
events: {
legendItemClick: function() {
var seriesIndex = this.index;
var series = this.chart.series;
if (this.visible && this.chart.restIsHidden) {
$(series).each(function(){
this.setVisible(true, false);
});
this.chart.restIsHidden = false;
} else {
$(series).each(function(){
this.setVisible(false, false);
});
this.show()
this.chart.restIsHidden = true;
}
return false;
}
},
showInLegend: true
}
}
