我是Highcharts的新手。我想实现这样的2个图表

charts

为此,我创建了一个自定义折线图组件,用highcharts替换现有的库。我创建的组件包含接口,

export interface LineChartProps {
  title?: string;
  xTitle?: string;
  yTitle?: string;
  chartWidth?: number;
  chartHeight?: number;
  seriesData: any[][];
  seriesColor: string[];
  gridLine?:boolean;
  name?: any;
}

修改之前的代码是

private getAlertTrendGraph = (alertTrendData: TrendType) => {
        /* Reading in the Alert Trend API Data and constructing the Chart Lines. */
        let result = ['Low', 'Medium', 'High'].map((keyValue, index) => {
            if (alertTrendData.values[keyValue] !== undefined) {

                let alertTrendValue = alertTrendData.values[keyValue].map((data) => {
                    return (parseInt(data, 10));
                });
                let color = '#FFFFFF';
                if (keyValue === 'Low') {
                    color = '#27AEF0';
                }
                else if (keyValue === 'Medium') {
                    color = '#FFC627';
                }
                else if (keyValue === 'High') {
                    color = '#ED3124';
                }

我无法得到准确的图表。有人能帮我一下吗。先谢了。

首先,我建议你在React中使用官方支持的Highcharts Package 器:highcharts-react-official
Package 器支持许多开箱即用的常见用例,并且使用它创建所需的图表非常容易。示例:https://codesandbox.io/s/highcharts-react-demo-nskz3y
但是,在您的示例中,您只需要呈现一个具有多个系列的LineChart组件,而不是呈现具有一个系列的多个LineChart组件。

const renderChart = () => {
    const seriesData = [];

    ["Low", "Medium", "High"].forEach((keyValue) => {
      const alertTrendValue = alertTrendData.values[keyValue].map((data) => {
        return parseInt(data, 10);
      });

      seriesData.push({
        color,
        data: alertTrendValue,
        type: "spline"
      });
    });
    return <LineChart seriesData={seriesData} />;
  };
