用react框架g2plot2.4.7版本 dualaxes slider的交互,例子

以下是使用React框架和g2plot 2.4.7版本实现DualAxes Slider交互的代码示例： ```jsx import React, { useState, useEffect } from 'react'; import { Chart, Line, DualAxes } from '@antv/g2plot'; import '@antv/g2plot/dist/g2plot.css'; const MyChart = () => { const [data, setData] = useState([ { year: '1991', value: 3, count: 10 }, { year: '1992', value: 4, count: 4 }, { year: '1993', value: 3.5, count: 5 }, { year: '1994', value: 5, count: 10 }, { year: '1995', value: 4.9, count: 3 }, { year: '1996', value: 6, count: 4 }, { year: '1997', value: 7, count: 5 }, { year: '1998', value: 9, count: 5 }, { year: '1999', value: 13, count: 4 }, { year: '2000', value: 15, count: 5 }, { year: '2001', value: 16, count: 6 }, { year: '2002', value: 18, count: 8 }, { year: '2003', value: 21, count: 9 }, { year: '2004', value: 22, count: 12 }, { year: '2005', value: 24, count: 7 }, { year: '2006', value: 26, count: 9 }, { year: '2007', value: 28, count: 13 }, { year: '2008', value: 30, count: 15 }, { year: '2009', value: 31, count: 17 }, { year: '2010', value: 32, count: 16 }, { year: '2011', value: 33, count: 18 }, { year: '2012', value: 34, count: 20 }, { year: '2013', value: 35, count: 22 }, { year: '2014', value: 36, count: 24 }, { year: '2015', value: 37, count: 26 }, { year: '2016', value: 38, count: 28 }, { year: '2017', value: 39, count: 30 }, { year: '2018', value: 40, count: 32 }, { year: '2019', value: 41, count: 33 }, { year: '2020', value: 42, count: 35 }, ]); const [chart, setChart] = useState(null); useEffect(() => { if (!chart) { const plot = new Chart({ container: 'container', autoFit: true, height: 500, padding: [40, 20, 40, 50], }); plot.data(data); plot.scale({ year: { type: 'time', mask: 'YYYY', range: [0, 1], }, value: { min: 0, max: 50, nice: true, }, count: { min: 0, max: 50, nice: true, }, }); plot.tooltip({ shared: true, showMarkers: false, }); const dualAxes = new DualAxes('dual', { data, xField: 'year', yField: ['value', 'count'], yAxis: [ { min: 0, max: 50, nice: true, }, { min: 0, max: 50, nice: true, }, ], meta: { value: { alias: 'Value', }, count: { alias: 'Count', }, }, slider: { start: 0.8, end: 1, }, }); plot.interaction('element-highlight-by-x'); plot.render(); setChart(plot); } }, [chart, data]); return <div id="container" />; }; export default MyChart; ``` 在上面的代码中，我们使用了`useState`来存储数据和图表对象。当组件渲染时，我们初始化了一个`Chart`对象，并将数据绑定到该对象上。我们还使用`DualAxes`组件创建了一个双轴图表，并将其添加到刚创建的`Chart`对象上。我们还为双轴图表添加了一个滑块交互，该交互允许用户选择某个时间范围内的数据。最后，我们使用`render`方法将图表渲染到页面上。 在上述代码中，我们使用了`@antv/g2plot`的`Line`和`DualAxes`组件来创建图表。我们还使用了`interaction`方法添加了一个元素高亮交互，该交互可以让用户在鼠标悬停时高亮显示当前数据点。
