If you have ever researched high performance and deeply customizable charts, then for sure you have come across to D3 charts. The D3 chart is a huge library and there are a number of posts to implement them. You can be creative without limits.
Let’s see what d3pie can do for you.
Configuration options include:
- Pie/donut charts.
- Title, subtitle, footer text, and control over placement.
- Inner and outer labels; choice of what data appears in each.
- Automatic percentage calculations.
- Unlimited data set size.
- Full control over font, font sizes, colors.
- Segment colors.
- Small segment grouping.
- Background color/transparency.
- Load, mouseover, and click effects.
- Callbacks for click, mouseover, and mouseout events.
- API for refreshing and recreating pies dynamically.
- Control over pie chart padding and pie chart x/y offsets.
Now let's start with the implementation
You only need two libraries:
Create a simple index.html
file, write the code in it, and open with the browser:
<html>
<head></head>
<body>
<div id="myPie"></div>
<script src="http://d3js.org/d3.v4.min.js" charset="utf-8"></script>
<!-- <script src="https://d3js.org/d3-selection.v1.js"></script> -->
<script src="d3pie.js"></script>
<script src="d3.min.js"></script>
<script>
var pie = new d3pie("myPie", {
header: {
title: {
text: "A very simple example pie"
}
},
data: {
content: [
{ label: "JavaScript", value: 50 },
{ label: "Ruby", value: 20 },
{ label: "Java", value: 30},
]
},
//Here further operations/animations can be added like click event, cut out the clicked pie section.
callbacks: {
onMouseoverSegment: function(info) {
console.log("mouse in", info);
},
onMouseoutSegment: function(info) {
console.log("mouseout:", info);
}
}
});
</script>
</body>
</html>
This will generate the following output:
Let's make it complex now.
Notice the line in above code: “Here further operations/animations can be added like click event, cut out the clicked pie section.”
Let’s create a file complex.html
and add this content:
<html>
<head></head>
<body>
<div id="pie"></div>
<button id="addData"> Add Data </button>
<script src="http://d3js.org/d3.v4.min.js" charset="utf-8"></script>
<script src="https://code.jquery.com/jquery-3.2.1.min.js" crossorigin="anonymous"></script>
<script src="d3pie.js"></script>
<script src="d3.min.js"></script>
<script>
var data = [
{ label: "1", value: 1 },
{ label: "2", value: 4 },
{ label: "3", value: 3 }
];
var pie = new d3pie("pie", {
data: {
content: data
}
});
$(function() {
var num = 4;
$("#addData").on("click", function() {
data.push({
label: num.toString(),
value: Math.floor(Math.random() * 10) + 1
});
pie.updateProp("data.content", data);
num++;
});
});
</script>
</body>
</html>
This will generate an output like this:
