我已经执行了在react-d3中获取图表的分步说明:
http://www.reactd3.org/get_start/
我将此添加到我的代码中,但我什么也没看到。
但是,如果我检查的话,我确实会看到一个SVG标签,里面有一些东西。
是否有一些元素被展平,或者您是否需要设置一些东西以在浏览器中显示 SVG?
我的确切代码如下所示:
import React from 'react';
var Chart = require('react-d3-core').Chart;
var LineChart = require('react-d3-basic').LineChart;
class WelcomeView extends React.Component {
render() {
var chartData = [
{"name":"Darron Weissnat IV","BMI":20.72,"age":39,"birthday":"2005-01-03T00:00:00.000Z","city":"East Russel","married":false,"index":0},
{"name":"Guido Conroy","BMI":25.17,"age":39,"birthday":"1977-04-20T00:00:00.000Z","city":"Scarlettland","married":true,"index":20},
{"name":"Miss Demond Weissnat V","BMI":21.44,"age":19,"birthday":"2007-06-09T00:00:00.000Z","city":"Savionberg","married":false,"index":21},
{"name":"Easton Mante","BMI":20.61,"age":43,"birthday":"2007-01-29T00:00:00.000Z","city":"Kutchberg","married":false,"index":22},
{"name":"Dayton Ebert","BMI":29.88,"age":20,"birthday":"1978-04-27T00:00:00.000Z","city":"West Wiley","married":true,"index":23}
]
var width = 700,
height = 300,
margins = {left: 100, right: 100, top: 50, bottom: 50},
title = "User sample",
chartSeries = [
{
field: 'BMI',
name: 'BMI',
color: '#ff7f0e'
}
],
// your x accessor
x = function(d) {
return d.index;
}
return (
<div>
<div>
<Chart
title={title}
width={width}
height={height}
margins= {margins}
>
<LineChart
margins= {margins}
title={title}
data={chartData}
width={width}
height={height}
chartSeries={chartSeries}
x={x}
/>
</Chart>
</div>
</div>
);
}
}
export default WelcomeView;
我想我正确地遵循了一切,所以我不确定我做错了什么。
更新 :
如果我在图表元素上方动态添加另一个 SVG 元素,例如圆形:
<svg height="100" width="100">
<circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red" />
</svg>
然后圆圈出现,SVG 元素的添加神奇地启动了图表的渲染过程。
很困惑为什么会发生这种情况:(
