Question

我想要在 highcharts 中的时间序列图表的线和区域的颜色相同。我附上jsfiddle的链接 这里图表的阴影区域和线条颜色是蓝色的，但我想要这个十六进制代码#70843A。谁能帮我？ https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/line-time-series

Answer 1

如果我理解正确的问题，你不想要那个渐变。

Highcharts 提供了它，特别是在您的工作示例中

plotOptions: {
        area: {
          fillColor: {
            linearGradient: {
              x1: 0,
              y1: 0,
              x2: 0,
              y2: 1,
            },
            stops: [
              [0, Highcharts.getOptions().colors[0]],
              [
                1,
                Highcharts.color(Highcharts.getOptions().colors[0])
                  .setOpacity(0)
                  .get("rgba"),
              ],
            ],
          }

这可以通过 setOpacity 进行更新。

[1, Highcharts.color(Highcharts.getOptions().colors[0]).setOpacity(1).get('rgba')]

正如它所说，您只需将不透明度设置为 1。全块颜色。

如果你只是想改变颜色本身，你可以将填充颜色设置为 CSS 颜色..

fillColor: '#FF0000',

如果您希望将线条颜色等设置为您使用的 HEX。

您可以在标记中设置lineColor ..

Green LineColour
