My lack of Javascript skills are really showing here, but I am having a problem.
I have built a chart using Highcharts.js and I am trying to customize the tooltip display. It is a range chart and by default point.y returns the low value. I have no idea how to return the high value.
Can anyone help? Here is the formatter code and I have also created a jsfiddle.
formatter: function() {
var s = '<b>'+ this.x +'</b>';
$.each(this.points, function(i, point) {
s += '<br/>Maximum Value: ?<br/>Minimum Value: ' + point.y
+ '<br/>Spread Value: Max-Min';
});
return s;
},

Each of objects from points array contain point property which is true object from Highcharts. Then you have access to point.high and point.low. See: http://jsfiddle.net/cCrLh/3/
tooltip: {
crosshairs: true,
shared: true,
formatter: function() {
var s = '<b>'+ this.x +'</b>';
$.each(this.points, function(i, point) {
s += '<br/>Maximum Value: ' + point.point.high + '<br/>Minimum Value: ' + point.point.low
+ '<br/>Spread Value: Max-Min';
});
return s;
},
shared: true
},

I have a JsFiddle here:

In the initial view, the tooltip shows daily volume.
The tooltip formatter code is as follows:
formatter: function() {
var result = '<b>' + Highcharts.dateFormat('%A, %b %e, %Y', this.x) + '</b>';
for (var i = 0; i < this.points.length; i++) {
var datum = this.points[i];
console.log(datum);
result += '<br />Original price: $' + datum.point.high.toFixed(2);
result += '<br />Dropped price: $' + datum.point.low.toFixed(2);
result += '<br />Daily volume: ' + datum.point.name;
}
return result;
}
But when I click 'all' the daily volume becomes undefined.
How do I get my daily volume to appear when I click 'All'?
By default data grouping is enabled in Highstock. The solution here is disabling it:
series: [{
name: 'Temperatures',
data: data,
dataGrouping: {
enabled: false
}
}]

I am using highcharts and i would like to customize tooltip.
My tooltip should show the reqName and reqVersion,but currently the tooltip is showing all the values of the 'tipValue' array.
When i hover over the column it shows me tooltip on each column as (1.1,1.0,1.2,1.2)
where as I would like the tooltip to show version
1.1 for column tpReq
1.0 for column opReq
1.2 for column Rex
1.2 for column tpReq
My xVaue is an array of ['tpReq','opReq','Rex','tpReq']
My yValue is an array of [5,8,5,1]
My tipValue is an array of ['1.1','1.0','1.2','1.2']
Here is my function to draw the highcharts
function drawchar(myXAxis,myYAxis,myTooltip)
{
var xValue = JSON.parse(XAxis);
var yValue = JSON.parse(YAxis);
var tipValue = JSON.parse(myTooltip);
var reqTypeChart = new HighCharts.Chart ({
...
...
xAxis: {
categories: xValue,
title: { 'My Requests'
text: null
},
},
....
series: [{
name: 'Status',
data: yValue
}],
legend: { enabled: false },
tooltip: {
formatter: function () {
return '<b>' + this.xValue + '</b><br/>' +
'IssueCount: ' + Highcharts.numberFormat(this.yValue, 0) + '</b><br/>' +
'AppVersion: ' + tipValue ;
}
...
});
}
Try this.
function drawchar(myXAxis, myYAxis, myTooltip) {
var xValue = JSON.parse(myXAxis);
var yValue = JSON.parse(myYAxis);
var tipValue = JSON.parse(myTooltip);
var data = [];
$.each(xValue, function (index, val) {
var tempObj = {
x: val,
y: yValue[index],
tipValue: tipValue[index]
}
data.push(tempObj);
});
// **UPDATED **
data.sort(function(a, b){
if(a.x < b.x) return -1;
if(a.x > b.x) return 1; return 0;
})
var reqTypeChart = new HighCharts.Chart({
xAxis: {
title: {
text: 'My Requests'
}
},
series: [
{
name: 'Status',
data: data
}
],
legend: {
enabled: false
},
tooltip: {
formatter: function () {
return '<b>' + this.point.x + '</b><br/>' +
'IssueCount: ' + Highcharts.numberFormat(this.point.y, 0) + '</b><br/>' +
'AppVersion: ' + this.point.tipValue;
}
}
});
}
Combine all three values into one array of objects and set that array as data source in series of highchart api. You'll get passed object inside formatter method of tooltip wrapped into this.point object.
I managed to solve this problem by changing the tooltip formater. So first find the index of xValue and find the corresponding tooltip value from tipValue array.
formatter: function () {
var index = xValue.indexOf(this.xValue);
var tip = tipValue[index];
return '<b>' + this.xValue + '</b><br/>' +
'IssueCount: ' + Highcharts.numberFormat(this.yValue, 0) + '</b><br/>' +
'AppVersion: ' + tip ;
When the highcharts tooltip is shared (all series shown in the tooltip), is there a way to set the order in which the series display in the tooltip?
Yes. Each point is an object in a array called points. If you want it in reverse order you can do that via:
tooltip: {
formatter: function () {
var s = '<b>' + this.x + '</b>';
$.each(this.points.reverse(), function () {
s += '<br/>' + this.series.name + ': ' +
this.y + 'm';
});
return s;
},
shared: true
},
If you want to do some other ordering then you need to provide more information.
I'm running into some problems with adding some information to tooltip.
Basically, my highcharts gets generated dynamically, and everything is working great, but I would like an additional field to show up in tooltip, and I cannot make it work.
Any help would be appreciated.
Here is the snippet of code I am using which is generating an "undefined" label:
tooltip: {
formatter: function () {
var s;
if (this.point.name) {
s = '' + this.point.name + ': ' + this.y + ' fruits';
} else {
s = '' + this.series.title + ': ' + this.y + ' ' + this.x;
}
return s;
}
},
And here is the jsfiddle: http://jsfiddle.net/9zN2M/2/
It looks like this.series does not have a title property.
It does have a name property, though, so you should be able to use this.series.name.
I want to display multiple series Data in tooltip on every column
tooltip: {
formatter: function() {
return '<span style="color:#D31B22;font-weight:bold;">' +this.series.name +': '+ this.y +'<br/>'+
'<b style="color:#D31B22;font-weight:bold;">'+this.x +'</b><span>';
}
},
and Data
series: [{
showInLegend: false,
name: 'Total Click',
data: [3000,200,50,4000],
color: '#9D9D9D'
}, {
showInLegend: false,
name: 'Total View',
data: [100,2000,3000,4000],
color: '#D8D8D8'
}]
I am using like this but in tool tip only one series data is showing at a time.
I want to display Data like this (Total View:100 and Total Click:3000 )
please try using this code
updated DEMO
tooltip: {
formatter: function() {
var s = [];
$.each(this.points, function(i, point) {
s.push('<span style="color:#D31B22;font-weight:bold;">'+ point.series.name +' : '+
point.y +'<span>');
});
return s.join(' and ');
},
shared: true
},
You need to use shared parameter http://api.highcharts.com/highcharts#tooltip.shared and then in formater iterate on each point.
If anybody looking for scatterplot, here is solution to show shared tooltip.
formatter: function(args) {
var this_point_index = this.series.data.indexOf( this.point );
var this_series_index = this.series.index;
var that_series_index = this.series.index == 0 ? 1 : 0; // assuming 2 series
var that_series = args.chart.series[that_series_index];
var that_point = that_series.data[this_point_index];
return 'Client: ' + this.point.name +
'<br/>Client Health: ' + this.x +
'<br/>' + this.series.name + ' Bandwidth: ' + this.y + 'Kbps' +
'<br/>' + that_series.name + ' Bandwidth: ' + that_point.y + 'Kbps';
}
