在React中动态更新Highcharts图表 [英] Dynamically update Highcharts chart in react
问题描述
我正在react-redux中使用highcharts-react-official来创建明细表.
I am using highcharts-react-official in react-redux to create a drilldown chart.
但是,当我单击栏上的向下钻取时,我也会更新一些道具,这些道具会导致组件重新渲染-似乎阻止了向下钻取事件.
However when I click on a bar to drilldown, I also update some props which causes the component to re-render - which seems to prevent the drilldown event.
I kind of gathered from Change series data dynamically in react-highcharts without re-render of the chart that I should use shouldComponentUpdate and getChart() to prevent re-render and instead dynamically update the data.
我的问题是getChart()对于正式的highcharts react包似乎不起作用.我收到了Uncaught TypeError:this.refs.chart.getChart不是一个函数
My issue is that getChart() doesn't seem to work for the official highcharts react package. I'm getting Uncaught TypeError: this.refs.chart.getChart is not a function
我是否打算使用另一种方法来获取和动态更新图表?还是我可以看的一些例子?
Is there an alternative I'm meant to be using to get and dynamically update the chart? Or some examples that I could look at?
此处仅包括render和shouldComponentUpdate部分:
Just including render and shouldComponentUpdate parts here:
shouldComponentUpdate(nextProps, nextState) {
let chart = this.refs.chart.getChart();
//dynamically update data using nextProps
return false;
}
render () {
const options = {
chart: {
type: 'column',
height: 300,
events: {
drillup: (e) => {this.drilledUp(e)}
}
},
plotOptions: {
series: {
events:{
click: (e) => {this.categoryClicked(e)}
}
}
},
xAxis: {type: "category"},
yAxis: {title: {text: 'Amount Spent ($)'}},
series: [{
name: 'weekly spending',
showInLegend: false,
data: this.props.transactionChartData.series_data,
cursor: 'pointer',
events: {
click: (e)=> {this.weekSelected(e)}
}
}],
drilldown: {
series: this.props.transactionChartData.drilldown_data
}
};
return (
<HighchartsReact
highcharts={Highcharts}
options={options}
ref="chart"
/>
)
}
推荐答案
在highcharts-react-official v2.0.0
中添加了allowChartUpdate
选项,该选项在您的情况下效果很好.通过使用此选项,您可以通过更新组件来阻止更新图表:
In highcharts-react-official v2.0.0
has been added allowChartUpdate
option, which should work great in your case. By using this option you can block updating the chart with updating the component:
categoryClicked() {
this.allowChartUpdate = false;
this.setState({
...
});
}
...
<HighchartsReact
ref={"chartComponent"}
allowChartUpdate={this.allowChartUpdate}
highcharts={Highcharts}
options={...}
/>
此外,要获取图表实例,请使用refs
:
Moreover, to get the chart instance use refs
:
componentDidMount(){
const chart = this.refs.chartComponent.chart;
}
