我创建了一个新的自定义按钮，我可以设置不同的背景图像而不是“圆形”或“三角形”吗？

谢谢查南

根据文档，形状是在Highcharts.Renderer.symbols集合中定义的。检查此对象会发现以下可用形状：

Highcharts.Renderer.prototype.symbols:
  arc: function (a,b,c,d,e){var f=e.start,c=e.r||c||d,g=e.end-1.0E-6,d=e.innerR,h=e.open,i=W(f),j=Z(f),k=W(g),g=Z(g),e=e.end-f<Aa?0:1;return["M",a+c*i,b+c*j,"A",c,c,
  circle: function (a,b,c,d){var e=0.166*c;return["M",a+c/2,b,"C",a+c+e,b,a+c+e,b+d,
  diamond: function (a,b,c,d){return["M",a+c/2,b,"L",a+c,b+d/2,a+c/2,b+d,a,b+d/2,"Z"]}
  exportIcon: function (a,b,c,d){return y(["M",a,b+c,"L",a+c,b+d,a+c,b+d*0.8,a,b+d*0.8,"Z","M",a+c*0.5,b+d*0.8,"L",a+c*0.8,b+d*0.4,a+c*0.4,b+d*0.4,a+c*0.4,b,a+c*0.6,b,a+c*0.6,b+d*0.4,a+c*0.2,b+d*0.4,"Z"])}
  printIcon: function (a,b,c,d){return y(["M",a,b+d*0.7,"L",a+c,b+d*0.7,a+c,b+d*0.4,a,b+d*0.4,"Z","M",a+c*0.2,b+d*0.4,"L",a+c*0.2,b,a+c*0.8,b,a+c*0.8,b+d*0.4,"Z","M",a+c*0.2,b+d*0.7,"L",a,b+d,a+
  square: function (a,b,c,d){return["M",a,b,"L",a+c,b,a+c,b+d,a,b+d,"Z"]}
  triangle: function (a,b,c,d){return["M",a+c/2,b,"L",a+c,b+d,a,b+d,"Z"]}
  triangle-down: function (a,b,c,d){return["M",a,b,"L",a+c,b,a+c/2,b+d,"Z"]}

您还可以通过扩展集合来添加自己的符号。例如，绘制一个简单的 X：

$.extend(Highcharts.Renderer.prototype.symbols, {
    anX: function (a,b,c,d){return["M",a,b,"L",a+c,b+d,"M",a+c,b,"L",a,b+d]}
});

您可以将图像设置为图标

http://jsfiddle.net/Udgb3/

 symbol: 'url(http://highcharts.com/demo/gfx/sun.png)',
                symbolX:5,
                symbolY:0
