如何用圆形图标制作剑道图表图例？

Question

我看到了其他答案，但它是三角形的。我真正需要的是如下图所示的圆形图标：

我尝试通过Circle Geometry API 自定义此Dojo example 中的“kendo.geometry.Rect”。但我需要帮助来理解我应该做什么。

Answer 1

您的圆形几何仅定义中心和半径。然后你需要使用 drawing.Circle:

visual: function (e) {
  // get color of current marker and label
  var color = e.options.markers.background;     
  var labelColor = e.options.labels.color;
  var rect = new kendo.geometry.Rect([0, 0], [100, 50]);
  var layout = new kendo.drawing.Layout(rect, {
    spacing: 5,
    alignItems: "center"
  });
  // create a circle geometry centered at x=10, y=5, with a radius of 5
  var CircGeometry = new kendo.geometry.Circle([10, 5], 5);
  // draw the circle using the geometry and set the color (could have no stroke)
  var MarkerCircle = new kendo.drawing.Circle(CircGeometry, {
    stroke: { color: color, width: 1 },
    fill: { color: color }
  });
  //Create the text label
  var label = new kendo.drawing.Text(e.series.name, [0, 0], {
    fill: {
      color: labelColor
    }
  });

  //Add circle and label to layout object
  layout.append(MarkerCircle, label);
  layout.reflow()

  return layout;
}
