通过实例初始化图表,图表未显示

描述

感谢作者的项目,大大方便了我的工作内容
我在使用时发现直接设置option可以渲染,但是通过实例去setOption,会无显示内容

代码片段

const Chart = () => {
	const chartRef = useRef<EChart>(null);

	useEffect(() => {
		chartRef.current?.setOption({
			xAxis: {
				type: 'category',
				data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
			},
			yAxis: {
				type: 'value',
			},
			series: [
				{
					data: [820, 932, 901, 934, 1290, 1330, 1320],
					type: 'line',
					smooth: true,
				},
			],
		});
	}, []);

	return (
		<View style={{ height: 300 }}>
			<EChart ref={chartRef} echarts={echarts} option={{}} />
		</View>
	);
};

作者你好,引入后未知报错,求解!!

报错

一点击该组件就报错

数组map动态创建EChart不显示

以列表列式动态创建EChart不报错也不显示,代码示例:
{
this.state.chartDataArr.map((item, index) => {
let cell =



return cell
})
}

h5动态渲染后无法显示图表

const [show, setShow] = useState(true);
{!!show && <EChart echarts={echarts} option={setChartData(xData, yData, "分")} />}
像这样通过button等去切换EChart的状态,EChart无法正常的显示和隐藏。

TypeError: Cannot read property 'forEach' of undefined H5报错

原因未知(可能是我在函数组件里用了这个),但是用这个可以解决,感觉不是最优解,觉得写成函数式组件可能可以解决,因为好多的错误都是 component.hooks里的

微信小程序中echart覆盖在了弹窗上面

[email protected]
[email protected]

您好:

  1. 微信小程序中设置taro UI的AtFloatLayout,会出现echart覆盖在弹窗上面。
  2. 设置某个view为 position: 'sticky', top: '0',echart也会覆盖在该view上面。

代码如下,运行结果如图。

import React from 'react';
import ReactEchartsCore from 'techarts';
import * as echarts from 'echarts/src/echarts';
import { AtFloatLayout } from 'taro-ui';
import 'taro-ui/dist/style/components/float-layout.scss';
const results = [
    { time: '2020/07/31', value: 88.8, rate: 99.9 },
    { time: '2020/06/30', value: 87.2, rate: 99.3 },
    { time: '2020/05/31', value: 89.9, rate: 103 },
    { time: '2020/04/30', value: 93.5, rate: 105.8 },
];
const onInit = (canvas, width, height, dpr) => {
    const chart = echarts.init(canvas, 'default', {
        width: width,
        height: height,
        devicePixelRatio: dpr,
    });
    canvas.setChart(chart);
    chart.setOption({
        series: [{ type: 'bar' }, { type: 'line' }],
        dataset: {
            dimensions: ['time', 'value', 'rate'],
            source: [
                { time: '2020/07/31', value: 88.8, rate: 99.9 },
                { time: '2020/06/30', value: 87.2, rate: 99.3 },
                { time: '2020/05/31', value: 89.9, rate: 103 },
            ],
        },
        xAxis: { type: 'category' },
        yAxis: [{}, {}],
    });
    return chart;
};
export default function IndexPage() {
    return (
        <View style={{ height: '2000px' }}>
            <AtFloatLayout isOpened title='这是个标题'>
                这是内容区
            </AtFloatLayout>
            <View
                style={{
                    height: '200px',
                    position: 'sticky',
                    top: '0',
                    backgroundColor: 'red',
                }}
            ></View>
            <ReactEchartsCore
                onInit={(canvas, width, height, dpr) => onInit(canvas, width, height, dpr)}
                echarts={echarts}
                style={{ height: '220px' }}
                option={{
                    series: [{ type: 'bar' }, { type: 'line' }],
                    dataset: {
                        dimensions: ['time', 'value', 'rate'],
                        source: [
                            { time: '2020/07/31', value: 88.8, rate: 99.9 },
                            { time: '2020/06/30', value: 87.2, rate: 99.3 },
                            { time: '2020/05/31', value: 89.9, rate: 103 },
                        ],
                    },
                    xAxis: { type: 'category' },
                    yAxis: [{}, {}],
                }}
            />
        </View>
    );
