I am seeking to implement specific behavior in highcharts regarding tooltips. The desired setup includes having two types of tooltips:
For the custom tooltip, a simple formatter can be utilized. However, the challenge lies with the shared tooltip. Is it feasible to share the default tooltip among certain series while implementing a custom one for others?
Thank you.
Yes, it is possible but you will need to implement a formatter and prepare the necessary logic for it. Take a look at this very basic demonstration here
customFormatter:function(){
var content = '',
currentX = this.x,
allSeries = this.point.series.chart.series;
if(this.series.options.shared) {
$.each(allSeries,function(index,series){
if(series.options.shared) {
$.each(series.data,function(j, dataPoint){
if(dataPoint.x === currentX) {
content += '<span style="color:'+series.color+';font-weight:bold;">'+series.name+'</span> value: ' + dataPoint.y + '<br/>';
}
});
}
});
} else {
content = 'not shared value: ' + this.y;
}
return content;
}
If you're looking for a workaround in the API to achieve a specific functionality, one way is to track which series the mouse hovers over:
var series1Selected=0;
...
series: [{
events: {
mouseOver: function () {
series1Selected = 1;
},
mouseOut: function () {
series1Selected = 0;
}
},
This approach allows you to customize the tooltip based on whether the mouse is over series 1 or not.
tooltip: {
formatter: function () {
if (series1Selected == 1) {
var s = '<b>Series 1</b>';
} else {
var s = '<b>Shared</b>';
$.each(this.points, function () {
s += '<br/>' + this.series.name + ': ' + this.y + 'm';
});
}
return s;
},
shared: true
},
While not perfect, this method can be used as a starting point for finding a solution.
