只有一个 highcharts 使用 react-grid-layout 可以调整大小

Question

I am building a dashboard using React-Grid-Layout that will consist of grids that will house widgets (ie charts, calendars etc.). Each grid will be draggable, responsive and resizable (widget in grid will resize too).

My code;

import React, { Component } from "react";
import { Responsive, WidthProvider } from "react-grid-layout";
import ReactHighcharts from "react-highcharts";
import Highcharts from "highcharts/highstock";
import HighchartsReact from "highcharts-react-official";
import "./styles/styles.css";
const ResponsiveGridLayout = WidthProvider(Responsive);

const styles = {
  fontFamily: "sans-serif",
  textAlign: "center"
};

Only one chart can resize according to grid height and width change. It seems I am only passing dimension change to one div and not the rest. How do I have all charts follow grid resize instead of just one?

Answer 1

Your reference points only to the last created chart, you need to get the chart related with resize event, for example by callback refs:

export default class App extends Component {
  constructor(props) {
    super(props);
    this.myRef = React.createRef();
    this.conRef = React.createRef();

    this.chartRefs = [];

    this.setChartRef = (ref) => {
      this.chartRefs.push(ref);
    };
  }

  render() {
    const gridItems = [...];
    const layout = [...];

    return (
      <ResponsiveGridLayout
        ...
        onResizeStop={function (e, layout) {
          this.chartRefs[layout.i - 1].chart.reflow();
        }.bind(this)}
      >
        {gridItems.map((item, i) => {
          return (
            <div key={item.id} ref={this.conRef} className="grid-item">
              ...
              <HighchartsReact
                ref={this.setChartRef}
                containerProps={{ style: { width: "100%", height: "100%" } }}
                options={config}
                // highcharts={Highcharts}
              />
            </div>
          );
        })}
      </ResponsiveGridLayout>
    );
  }
}
