在chartist.js中为SVG数据点添加大纲

Question

我正在玩Chartist.js,只是想知道你是否可以给我一些手工将一些样式应用到SVG.这是我的代码如下:

jQuery的:

new Chartist.Line('.ct-chart', {
  labels: [1, 2, 3, 4, 5, 6, 7, 8],
  series: [
    [5, 9, 7, 8, 5, 3, 5, 4]
  ]
}, {
  low: 0,
  showArea: true
});

HTML:

<div class="ct-chart ct-perfect-fourth"></div>

CSS:

.ct-chart .ct-series.ct-series-a .ct-area { fill: orange; }
.ct-chart .ct-series.ct-series-a .ct-line { stroke: orange; }
.ct-chart .ct-series.ct-series-a .ct-point { stroke: orange; }

body { background: #203135; }

我只是试图模拟他们在运球时发现的这个令人敬畏的设计所拥有的东西,其中每个数据点都有一个深色阴影/类似背景阴影的轮廓.我已经尝试在CSS中使用轮廓,但它在数据点周围产生一个黑色方块(或我选择的任何颜色),我无法弄清楚如何将它四舍五入

最后,这里是我已经在jsFiddle中的内容 - http://jsfiddle.net/andyjh07/gLnkwLj0/

您可以用<line>元素替换数据点默认<circle>元素.这样您就可以控制圆形笔触颜色,宽度和填充颜色.

DEMO

var chart = new Chartist.Line('.ct-chart', {
  labels: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  series: [
    [5, 9, 7, 8, 5, 3, 5, 4, 9, 23],
  ]
}, {
  low: 0,
  showArea: true,
  lineSmooth: Chartist.Interpolation.simple({
    divisor: 2
  }),
});

chart.on('draw', function(data) {
  if (data.type === 'point') {
    var circle = new Chartist.Svg('circle', {
      cx: [data.x],
      cy: [data.y],
      r: [7],
    }, 'ct-circle');
    data.element.replace(circle);
  }
});

  .ct-chart .ct-series.ct-series-a .ct-line {stroke: orange;stroke-width: 3px;}
  .ct-circle {fill: orange;stroke-width: 5;stroke: #203135;}
  body {background: #203135;}
</style>
<div class="ct-chart ct-perfect-fourth"></div>
