I have been trying to achieve a chart like below using Highcharts library.
All i have been able to achieve is this http://jsfiddle.net/HpdwR/1489/ . So is there a way i could control how much the outer circle covers and its color. Also putting a title at the center of the chart.
Here is the config i have used to draw the chart
{
chart: {
renderTo: 'container',
type: 'pie'
},
title: {
text: 'Browser market share, April, 2011'
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
plotOptions: {
pie: {
shadow: false
}
},
tooltip: {
formatter: function() {
return '<b>' + this.point.name + '</b>: ' + this.y + ' %';
}
},
series: [{
name: 'Browsers',
data: [
["Chrome", 70]
],
size: '60%',
innerSize: '60%',
showInLegend: true,
dataLabels: {
enabled: false
}
}]
}
I would also like to know if there are any other js libraries that could draw the same.

You can use solid-gauge type of chart with circle background (instead of default arc).
pane: {
center: ['50%', '50%'],
size: '100%',
startAngle: 0,
endAngle: 360,
background: {
backgroundColor: 'black',
innerRadius: '0%',
outerRadius: '80%',
shape: 'circle'
}
},
plotOptions: {
solidgauge: {
dataLabels: {
enabled: true,
y: -25,
borderWidth: 0,
useHTML: true,
format: '<div style="text-align:center"><span style="font-size:45px;color:#fff;">{y}</span><br/>' +
'<span style="font-size:12px;color:silver">%</span></div>'
}
}
},
Example:
http://jsfiddle.net/12kwyftq/1/
you can use start angle ,end angle to make it desired view
startAngle: -90,
endAngle: 90,
center: ['50%', '75%']

I have a nested pie chart (two pie chart series, one an outer "doughnut" around the other). The inner pie chart needs to mainly use inner-positioned labels, but sometimes there isn't enough room and they overlap:
How can I get this to not overlap? Is there a way to switch the overlapping labels or those that can't fit inside their slices to be outer-positioned instead? Or some other strategy to make these readable? Using 100% outer positioned labels works, but because of the outer pie chart there isn't much room and it's much harder to read because the outer pie chart also has its own set of outer-positioned labels.
Series def:
seriesOpt = [{
encode: {
value: "value",
itemName: "name"
},
type: "pie",
startAngle: 90,
//minShowLabelAngle: 0.05, // buggy, throws internal javascript error
avoidLabelOverlap: true,
datasetIndex: 0,
name: "inner",
radius: [0, insideRadius??"40%"],
label: {
show: true,
position: "inside"
distanceToLabelLine: 10,
alignTo: "none",
overflow: "truncate",
formatter: '{name|{b}}\n{pct|{d}%}',
rich: {
pct: {
color: '#999'
}
},
labelLine: {
show: false
}
},{
encode: {
value: "value",
itemName: "name"
},
type: "pie",
startAngle: 90,
//minShowLabelAngle: 0.05, // buggy, throws internal javascript error
avoidLabelOverlap: true,
datasetIndex: 1,
name: "outer",
radius: [outsideInnerRadius??"60%",outsideOuterRadius??"75%"],
label: {
show: true,
position: "outside",
distanceToLabelLine: 10,
alignTo: "none",
overflow: "truncate",
formatter: '{name|{b}}\n{pct|{d}%}',
rich: {
pct: {
color: '#999'
}
},
labelLine: {
show: true,
length: 60,
length2: 15
}
}]
You should tweak series-pie.labelLayout.
Here is an example:
const data = [
{
name: 'Foo',
value: 10
},
{
name: 'Bar',
value: 20
},
{
name: 'Baz',
value: 15
},
{
name: 'Qux',
value: 500
}
];
let option = {
series: [
{
type: 'pie',
radius: ['120px', '90px'],
center: ['50%', '50%'],
data,
label: {
position: 'inner'
},
labelLayout: {
moveOverlap: 'shiftY' // <--- HERE
}
},
{
type: 'pie',
radius: '42px',
center: ['50%', '50%'],
data,
label: {
position: 'inner'
},
labelLine: {
showAbove: true
},
// ========== THERE ==========
labelLayout: {
x: 131,
moveOverlap: 'shiftY'
}
// ====================
}
]
};
let myChart = echarts.init(document.getElementById('main'));
myChart.setOption(option);
#main {
width: 300px;
height: 300px;
}

I have doughnut chart using chartsjs, and also I used multi layer with cutoutPercentage.
The First Layer (Black color) is the Total and the second layer (Red Color) complete is the running value.
type: 'doughnut',
data: {
datasets: [
{
data: Total,
fill: true,
backgroundColor:'rbg(242, 133, 0)',
borderWidth: 3,
weight:1,
},{
data: complete,
fill: true,
backgroundColor:'rgb(255,36,0)',
borderWidth: 3,
weight:1,
}
]
},
options: {
responsive: true,
rotation: 1 * Math.PI,
circumference: 1 * Math.PI,
legend: {
display: false
},
tooltip: {
enabled: false
},
cutoutPercentage: 70,
},
This is what I need,2nd layer is running until reach the total.
In case you need a generic solution, you can use the Plugin Core API and define a beforeInit hook that modifies the chart configuration to fit your needs.
Please take a look at below runnable code and see how it could be done.
new Chart('runningValue', {
type: 'doughnut',
plugins: [{
beforeInit: chart => {
chart.data.datasets = [{
data: [chart.data.total],
backgroundColor: chart.data.totalColor,
borderWidth: 3
},
{
data: [chart.data.complete, chart.data.total - chart.data.complete],
backgroundColor: [chart.data.completeColor, '#fff'],
borderWidth: 3
}
]
}
}],
data: {
total: 50,
complete: 35,
totalColor: 'rbg(242, 133, 0)',
completeColor: 'rgb(255,36,0)'
},
options: {
rotation: -90,
circumference: 180,
plugins: {
legend: {
display: false
},
tooltip: {
enabled: false
}
},
cutout: '70%'
}
});
canvas {
max-height: 100px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.7.1/chart.js"></script>
<canvas id="runningValue"></canvas>
Simply define two values and two background colors on the second dataset as shown in the runnable code below.
const total = 50;
const complete = 35;
new Chart('runningValue', {
type: 'doughnut',
data: {
datasets: [{
data: [total],
backgroundColor: 'rbg(242, 133, 0)',
borderWidth: 3
},
{
data: [complete, total - complete],
backgroundColor: ['rgb(255,36,0)', '#fff'],
borderWidth: 3
}
]
},
options: {
rotation: -90,
circumference: 180,
plugins: {
legend: {
display: false
},
tooltip: {
enabled: false
}
},
cutout: '70%'
}
});
canvas {
max-height: 100px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.7.1/chart.js"></script>
<canvas id="runningValue"></canvas>
I have data from 10/19 to 11/01 and I am plotting it using a scattered Highcharts plot (v4.1.10, cannot upgrade). For some reason my x-axis is showing 10/18, but I want it to start with 10/19. I tried using pointStart, but this did not work. Any suggestions on how to get the correct starting date to show in my x-axis?
Highcharts.chart('container', {
yAxis: {
gridLineWidth: 0.5,
gridLineColor: '#D6D6D6',
tickInterval: 5,
dashStyle: 'LongDash',
lineColor: '#D6D6D6'
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
day: '%m/%d',
week: '%d/%b',
month: '%b/%y',
year: '%Y'
},
title: {
enabled: true,
text: 'date'
},
gridLineWidth: 0,
lineColor: '#D6D6D6',
lineWidth: 0.5,
startOnTick: true
},
plotOptions: {

}
}

}
},

},
tooltip: {

var s = '<b>' + Highcharts.dateFormat('%m/%d %H:%M:%S', this.x)

return s;
},
},

You can set the x axis min value:
xAxis: {
min:1539950400000
Example: http://jsfiddle.net/jlbriggs/dwnx6o8e/9/
Depending on the data and other options, you may need to look at other properties, like startOnTick, tickInterval, etc.
I'm using HighCharts to display charts on my site.
What I'd like to achieve is just a line chart with (zoomable) Date-Time X-Axis and numbers in Y-Axis.
But the result is messed up:
I load data by an ajax call, create an array and use chart.series[0].setData(chartData); to set the chart's data. Below is a sample for chartData:
[[1343071800000, 17], [1343158200000, 171], [1343244600000, 291], [1343075400000, 18],
[1343161800000, 74], [1343248200000, 293], [1343165400000, 183], [1343251800000, 296]]
Also, I use DotNetHighCharts since I'm using ASP.NET MVC 3, but the generated javascript to create the chart is as follows:
chart = new Highcharts.Chart({
chart: { renderTo:'chart_container' },
legend: { align: 'left', borderWidth: 0, floating: true, layout: 'horizontal', verticalAlign: 'top', y: 20 },
plotOptions: { series: { cursor: 'pointer', marker: { lineWidth: 1 }, point: { events: { click: function() { alert(Highcharts.dateFormat('%A, %b %e, %Y', this.x) +': '+ this.y +' visits'); } } } } },
subtitle: { text: 'Source: Google Analytics' },
title: { text: 'Daily visits at www.highcharts.com' },
tooltip: { crosshairs: true, shared: true },
xAxis: { gridLineWidth: 1, labels: { align: 'left', x: 3, y: -3 }, tickInterval: 604800000, tickWidth: 0, type: 'datetime' },
yAxis: [{ labels: { align: 'left', x: 3, y: 16, formatter: function() { return Highcharts.numberFormat(this.value, 0); } }, showFirstLabel: false, title: { text: '' } }, { gridLineWidth: 0, labels: { align: 'right', x: -3, y: 16, formatter: function() { return Highcharts.numberFormat(this.value, 0); } }, linkedTo: 0, opposite: true, showFirstLabel: false, title: { text: '' } }],
series: [{ name: 'All visits' }]
Your dataset is not in chronological order. So the charting system is joining all the points as best it can.
For time-based series it is always best to sort your time from earliest to latest.
I add Ext.draw.Component inside grid cell as column renderer:
renderer: function(_value){
var id = Ext.id();
Ext.Function.defer(function(){
Ext.create('Ext.draw.Component', {
minWidth: width,
id: 'timer-' + id,
width: (_value * width),
style: {
position: 'absolute',
'z-index': '10000000',
},
height: 17,
renderTo: id,
resizable: {
dynamic: true,
pinned: true,
handles: 'w e',
widthIncrement: width,
},
gradients: [{
id: 'grad1',
angle: 270,
stops: {
0: {
color: '#6594cf'
},
1: {
color: '#c6d8ed'
},
99: {
color: '#5f96db'
},
100: {
color: '#6594cf'
}
}
}],
items: [{
type: 'rect',
fill: 'url(#grad1)',
width: '100%',
height: '100%',
x: 0,
y: 0
}],
draggable: {
constrain: false,
},
listeners: {
}
});
}, 25);
return '<div id="' + id + '" style="width:1000px;" class="timers" />';
}
I need to know, how to drag this draw component only by x-axis. And I need name of listeners, whitch called on drag and on resize.
There is listner resize, but funciton return only new width and height (or I dont know some thing), I need to know, to whitch resizable handle was user pooled - left or right?
