我尝试使用React在D3.js上添加标签到我的线图。我编写了下面的代码,它将显示轴但文本节点不可见但我可以在开发人员工具的DOM中看到它。
import React, { PropTypes, Component } from 'react';
import * as d3 from 'd3';
export default class Axis extends Component {
static propTypes= {
h: PropTypes.number.isRequired,
axis: PropTypes.func.isRequired,
axisType: PropTypes.oneOf(['x', 'y']).isRequired,
}
componentDidMount = () => { this.renderAxis(); }
componentDidUpdate = () => { this.renderAxis(); }
renderAxis = () => {
const node = this.axisRef;
d3.select(node).call(this.props.axis);
// const domain = d3.selectAll('path.domain');
const ticks = d3.selectAll('g.tick');
ticks.select('text').style('font-family', 'Poppins');
ticks.select('text').style('fill', 'black');
}
render() {
const translate = `translate(0,${(this.props.h)})`;
return (
<g
ref={(node) => { this.axisRef = node; }}
className="axis"
transform={this.props.axisType === 'x' ? translate : ''}
>
<text value={this.props.axisType === 'x' ? 'x axis' : 'y axis'}>Hello world</text>
</g>
);
}
}

请参考此处的示例:https://bl.ocks.org/d3noob/23e42c8f67210ac6c678db2cd07a747e
message['chat']['id']
这基本上将添加一个文本并将其放置在x轴的中心,即width / 2(如果有填充,则为总和)
