有什么办法可以使用c3js更改标签? [英] Is there any way to change a label with c3js?
问题描述
我正在使用新的 c3js 库.有什么方法可以更改图表中数据的标签吗?我有一个条形图，其中每个条形都是美元值.我希望每个条形的标签为$ 100而不是100.如果将值设置为$ 100，则库将无法制作图表.有没有办法更改标签-如果不是基础值?
I am using the new c3js library. Is there any way to change a label for a piece of data in the chart? I have a bar chart where each bar is a dollar value. I want the labels for each bar to be $100 instead of 100. If I set the value to $100 then the library cannot make the chart. Is there any way to change the label -- if not the underlying value?
推荐答案
您可以为数据标签和轴刻度指定格式.看下面的例子.
You can specify the formatting for both the Data Labels and the Axis Ticks. Have a look at the example below.
<!doctype html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="./css/c3.css">
<script src="./js/d3.min.js"></script>
<script src="./js/c3.min.js"></script>
</head>
<body>
<div class='chart'>
<div id='chart'></div>
</div>
<script>
var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 400, 150, 250],
['data2', 130, 100, 140, 200, 150, 50]
],
type: 'bar',
labels: {
format: {
y: d3.format("$,")
//y: function (v, id) { return "Custom Format: " + id; }
}
}
},
axis : {
y : {
tick: {
format: d3.format("$,")
//format: function (d) { return "Custom Format: " + d; }
}
}
}
});
</script>
</body>
</html>
在d3.js中查看格式设置选项，也可以编写自己的函数(请参见注释)上面的代码).
Check out the formatting options in d3.js or you can write your own function (see commented out code above).
