标尺

基本表示示例

const width = 130;

const frags = scale.blueprint.fragments({ width, height: 16, padding: 5, space: 42, arrowSize: 7, vertical: false }, theme.scale.active);

const n = {
  x: 0,
  y: 0,
  children: frags.elements,
  texts: [
    {
      x: width / 2,
      content: "20px",
      opts: textOpts,
    },
  ],
};

graph.updateQueue(0, [[n]]);

多段标尺示例

const frags2 = scale.multiple.fragments({ segements: [{ width: 130, space: 36 }, { width: 90, space: 36 }], height: 16, padding: 5, arrowSize: 7, vertical: true }, theme.scale.active);
const n = {
    x: 0,
    y: 0,
    texts: [
        {
            y: 130 / 2,
            content: "54cm",
            opts: {
                ...textOpts,
                width: 42,
                fill: "#8ac"
            }
        },
        {
            y: 130 + 90 / 2,
            content: "32cm",
            opts: {
                ...textOpts,
                width: 42,
                fill: "#8ac"
            }
        }
    ],
    children: frags.elements,
};

graph.updateQueue(0, [[n]]);
