NET MVC Project, where I use Highcharts. In my charts i have columns and a spline.
I have already implemented drilldown for my chart and it works perfectly, but only for the columns. On the first level the columns and the spline is shown, but when I trigger drilldown only the columns are shown. data2 should be the spline.
var mychart = Highcharts.chart('container', {
chart: {
zoomType: 'xy',
spacingBottom: 40,
spacingTop: 40,
events: {
// DRILLDOWN
drilldown: function (e) {
//Some variables id, func
$.getJSON(`/Home/GetDataForMinuteDrilldown?id=${id}&function=${func}`, function (data) {
console.log(data);
var durationArrMinutes = data.map(function (item) {
return item['minuteavg'];
});
var errorArrayMinutes = data.map(function (item) {
return item['errorsperminute']
});
var minuteArray = data.map(function (item) {
return {
name: drill + ":" + item['minute'],
y: item['minuteavg'],
drilldown: item['minute']
};
});
data2 = {
name: 'Errors per Minute',
type: 'spline',
data: errorArrayMinutes,
tooltip: {
valueSuffix: ' '
}
}
data = {
name: 'Average Duration per Minute',
type: 'column',
yAxis: 1,
data: minuteArray,
tooltip: {
valueSuffix: ' ms'
},
data2 //I think this is the error, but I i know no solution
}
console.log('Data:')
console.log(data);
mychart.hideLoading();
mychart.addSeriesAsDrilldown(e.point, data);
});
}
}
},
title: {
text: 'Performance and Error Analytics'
},
subtitle: {
text: 'Analytics of: ' + func
},
xAxis: [{

crosshair: true
}],

}
},

}

}
},

},

},
series: [{
name: 'Average Duration per Hour',
type: 'column',
yAxis: 1,
data: durationPerHourArray,
tooltip: {
valueSuffix: ' ms'
}
}, {
name: 'Errors',
type: 'spline',
data: errorArray,
tooltip: {
valueSuffix: ' '
}
}],
drilldown: {
activeAxisLabelStyle: {
textDecoration: 'none',
fontStyle: 'normal',
color: 'black'
},
series: []
}
});
The addSeriesAsDrilldown method allows to add only one series to drilldown. From source code:
Chart.prototype.addSeriesAsDrilldown = function (point, options) {
this.addSingleSeriesAsDrilldown(point, options);
this.applyDrilldown();
};
Instad of addSeriesAsDrilldown, you can use internal addSingleSeriesAsDrilldown method to add both series and call applyDrilldown:
mychart.addSingleSeriesAsDrilldown(e.point, data);
mychart.addSingleSeriesAsDrilldown(e.point, data2);
mychart.applyDrilldown();

I Used Hightcharts before. This was my code:
function drawLine(data, title, selector, name) {
$(selector).highcharts({
title: {
text: title,
x: -20 //center
},
xAxis: {
categories: data.map(function(i) { return new Date(parseInt(i.Index.substr(6))).toDateString(); })
},
yAxis: {
title: {
text: 'Count '
},
plotLines: [
{
value: 0,
width: 1,
color: '#808080'
}
]
},
tooltip: {
valueSuffix: ''
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [
{
name: name,
data: data.map(function(i) { return i.Value; })
}
]
});
}
How can i do the same with Highstock?
Problem in:
xAxis: {
categories: data.map(function(i) { return new Date(parseInt(i.Index.substr(6))).toDateString(); })
}
Highstock does not contain "categories".
Can you please take a look at this demo and let me know why I am not able to set the other side yAxis , as well?
$(function () {
$('#chart2').highcharts({

}
},
xAxis: {

},
yAxis: [{ // Primary yAxis

}
}, { // Secondary yAxis

}
},
labels: {

}
},
opposite: true
}],
legend: {
enabled: false
},
tooltip: {
formatter: function() {
return this.x +
' is <b>'+ this.y +'</b>';
}
},
series: [{
data: [{
name: 'Roads',
y: 200
}, {
name: 'Powerlines',
color: '#FF00FF',
y: 50
}]
}]
});
});
I find some sample on the Highcharts API and I tried to follow them on my demo but they didn't work!
Highcharts : bar chart with multiple y axes
I have corrected the problem with your code: DEMO
You will have to pass series data for each y-axis individually:
series: [{
name: 'Rainfall',
type: 'column',
yAxis: 1,
data: [49.9, 71.5],
tooltip: {
valueSuffix: ' mm'
}
}, {
name: 'Temperature',
type: 'column',
data: [7.0, 6.9],
tooltip: {
valueSuffix: ' °C'
}
}]
Well, I think you need to fix your series object. How about this:
series : [{
data : [{
name : 'Roads',
y : 200
}, {
name : 'Powerlines',
color : '#FF00FF',
y : 50
}
]
},
{
yAxis : 1,
data : [{
name : 'Roads',
y : 30
}, {
name : 'Powerlines',
color : '#FF00FF',
y : 10
}
]
}
]
Also you need to add yAxis : 1 as an id to axis (you can explicitly set the id of an axis to make sure)
Kindly take a look at following fiddle in which i tried to remove the categories but on removing categories its placing numbers instead of it by default and also showing those numbers in tooltip.
All I am trying to do is that categories or numbers doesnot display on chart or on tooltip and only stackedbar appears on the chart , So kindly let me know how can i do it .Thanks,
http://jsfiddle.net/EJFsH/3/
$(function () {
var data = [ {
name: 'Year 2008',
data: [0, 914, 4054, 732, 34]
}];
data = $.grep(data, function (category) {
return $.grep(category.data, function (item) {
return item > 0;
}).length > 0;
});

},

});
});
I'm not 100% sure of what you are asking for. But, to turn off the XAxis or yAxis labels, juse labels : {enabled:false} and to change the tooltips use tooltip:{formatter: function() {...}}
see this fiddle:
http://jsfiddle.net/6ypq4/
xAxis: {
title: {
text: null
},
labels : {
enabled: false
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify',
enabled: false
}
},
tooltip: {
formatter: function() {
return this.y + ' millions';
}
},
I have a Highcharts Graph that is displaying three different energy costs. I can't seem to get my legend to show nor can I get the axis titles to show.
The Legend should have the titles on; Gas, Electric, Oil and they should also be on the axis too.

Can anyone help me show the legend and axis titles?
The legend also needs to be click-able so that each line disappears and reappears when clicked.
Many thanks for your help

For legend you should add enabled parameter with true value.
http://jsfiddle.net/HHEfW/5/
legend: {
enabled: true
}
yAxis titles don't work, because are not defined, so you should add title parameter with text value. http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/stock/xaxis/title-text/
I need to set different colors for each column in Highcharts graph dynamically. My Highcharts graph is:
options = {
chart: {
renderTo: 'chart',
type: 'column',
width: 450
},
title: {
text: 'A glance overview at your contest’s status'
},
xAxis: {
categories: ['Approved Photos', 'Pending Approval Photos',
'Votes', 'Entrants'],
labels: {
//rotation: -45,
style: {
font: 'normal 9px Verdana, sans-serif, arial'
}
}
},
yAxis: {
allowDecimals: false,
min: 0,
title: {
text: 'Amount'
}
},
legend: {
enabled: false
},
series: []
};
series = {
name: "Amount",
data: [],
dataLabels: {
enabled: true,
color: '#000000',
align: 'right',
x: -10,
y: 20,
formatter: function () {
return this.y;
},
style: {
font: 'normal 13px Verdana, sans-serif'
}
}
};
The data is set this way:
for (var i in Data) {
if (parseInt(Data[i]) != 0) {
series.data.push(parseInt(Data[i]));
} else {
series.data.push(null);
}
}
options.series.push(series);
chart = new Highcharts.Chart(options);
How can I dynamically set different colors for each data point in this loop?
Here is another solution with the latest version of Highcharts (currently 3.0).
Set the colorByPoint option to true and define the color sequence that you want.
options = {
chart: {...},
plotOptions: {
column: {
colorByPoint: true
}
},
colors: [
'#ff0000',
'#00ff00',
'#0000ff'
]
}
Here is an example based upon Highcharts Column with rotated labels demo
When you add the value to the series.data you can also set the color using the point options e.g
series.data.push({ y: parseInt(Data[i]), color: '#FF0000' });
For more details about the point options see https://api.highcharts.com/class-reference/Highcharts.Point#color
Try either of these approaches:
Approach 1:
Highcharts.setOptions({ colors: ['#3B97B2', '#67BC42', '#FF56DE', '#E6D605', '#BC36FE'] });
Approach 2:
var colors = ['#3B97B2', '#67BC42', '#FF56DE', '#E6D605', '#BC36FE', '#000'];
$('#bar_chart').highcharts({
chart: {
type: 'column'
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: ''
}
},
legend: {
enabled: false
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: false
}
}
},
series: [{
name: '',
colorByPoint: true,
data: [{
name: 'Blue',
y: 5.78,
color: colors[0]
}, {
name: 'Green',
y: 5.19,
color: colors[1]
}, {
name: 'Pink',
y: 32.11,
color: colors[2]
}, {
name: 'Yellow',
y: 10.04,
color: colors[3]
}, {
name: 'Purple',
y: 19.33,
color: colors[4]
}]
}]
});
i had colors from API response and 2 series. second series with dynamic colors.
following is sample to set dynamic colors while series mapping.
const response = [{
'id': 1,
'name': 'Mango',
'color': '#83d8b6',
'stock': 12.0,
'demand': 28,
},
{
id ': 2,
'name': 'Banana',
'color': '#d7e900',
'stock': 12.0,
'demand': 28,
}
];
let chartData: {
categories: [],
series: []
};
chartData.categories = response.map(x => x.name);
chartData.series.push({
name: 'Series 1',
type: 'column',
data: response.map(x => x.demand)
});
chartData.series.push({
name: 'Series 2',
type: 'column',
data: response.map(x => ({
y: x.stock,
color: x.color // set color here dynamically
}))
});
console.log('chartData: ', chartData);
