解决方案
如果我理解正确的问题,你不想要那个渐变。
Highcharts 提供了它,并且在您的工作示例中,特别是
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.. 来更新。
[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。
如果您只想更改颜色本身,您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lineColor
在标记中设置..
该文档的布局非常好。
