A data visualization chart library for dynamic interaction.
ccd3 does not pay attention to the combination of each part of the chart, but pays more attention to the state change of the chart.
Because it's state driven, diagrams are easy to use and interact with.
But the configurability is weak.
If charts don't meet your needs, you can use othe chart libraries. Of course, you can use d3.js for all kinds of customization like me, but it takes a lot of effort.
npm install ccd3
Detailed description of each option item
step1: Set a div with width and height.
<body>
<div id="dom" style="width: 970px;height: 600px;"></div>
</body>step2: Beacase ccd3 is based on d3.js. So you should do this:
<body>
<div id="dom" style="width: 970px;height: 600px;"></div>
<script src="../../node_modules/d3/dist/d3.js"></script>
<script src="../../dist/ccd3.js"></script>
</body>Then you got two global object :
d3ccd3
ccd3 has a init method.
ccd3.init(id,option,[theme])
id: dom's idoption: Each option is used to describe the various parts of the diagramtheme: An global color scheme
You can call it, and then it will return an array.The first element is the chart, and the second is the method which can change the state of the chart.
<body>
<div id="dom" style="width: 970px;height: 600px;"></div>
<script src="../../node_modules/d3/dist/d3.js"></script>
<script src="../../dist/ccd3.js"></script>
<script>
const option = {}
const theme = {}
const [bar, setBar] = ccd3.init('dom', option, theme);
</script>
</body>Each chart is made up of option, themeand data.
-
option: Each option is used to describe the various parts of the diagram. -
theme: An global color scheme. -
data: A data structure for each chart.
- The configuration item must be complete and cannot be defaulted.
- Configuration items are completely semantic based. You can easily understand them.
- The
nameproperty is used to identify the chart. So each chart has a uniquename.
const option = {
name: 'verticalBar',
verticalBar: {
uniqueKey: 'name',
on: {
click: (event, value, data) => { console.log(event, value, data) }
},
animation: {

ease: d3.easeBounce
}

let str = "";
for (let key in data) {
str += `${key} : ${data[key]} <br/>`;
}
return str;
},
transition: {
duration: 300,
ease: d3.easeBackOut
}
},

}- An global color scheme for all charts
const theme = {
name: 'default',
primary1: '#93b7e3',

}- A chart has a data structure, which is not universal.
const data = [
{ name: 'apple', value: 150 },
{ name: 'banana', value: 200 },
{ name: 'orange', value: 120 },
{ name: 'mango', value: 100 },
{ name: 'pineapple', value: 210 },
{ name: 'watermelon', value: 160 },
{ name: 'pitaya', value: 331 },
{ name: 'strawberry', value: 105 }
];When you prepared the option and theme,you can init the chart, and get a chart object and a method to set chart's state.
After you prepared the data,you can render the chart, by setState.
Like this :
//init chart
const [bar, setBar] = ccd3.init('dom', option, theme);
//initial data
const data = [
{ name: 'apple', value: 150 },
{ name: 'banana', value: 200 },
{ name: 'orange', value: 120 },
{ name: 'mango', value: 100 },
{ name: 'pineapple', value: 210 },
{ name: 'watermelon', value: 160 },
{ name: 'pitaya', value: 331 },
{ name: 'strawberry', value: 105 }
];
// set state
setBar(data);
// Asynchronous operation
setTimeout(() => {
// change the state
data.sort((a, b) => a.value - b.value);
// change the theme
theme.title.textStyle.x = "100";
// set the state again
bar.render(data,theme);
