但对我来说什么都不管用，当我看到这一点时，我无法理解这个问题

当我理解了潜在的问题后，我会用一些例子来更新我的文章，使之更适合未来的读者

干杯

编辑（解决方案+解释）：

在以下JSFIDLE中查找已解决的问题：

所以问题是因为

rangeRound（）

与一个简单的

插值（'basis'）

医生说：

线性。范围圆形（值） 将比例的输出范围设置为指定的值数组，同时将比例的插值器设置为d3.interpolateRound。这是一个方便的例程，用于确定刻度输出的值应为精确整数的时间，例如避免抗锯齿瑕疵。也可以在应用刻度后手动四舍五入输出值

我想我应该将它与

interpolateRound

函数一起使用

---

希望这能帮助别人。如果我在这里说错了什么，请不要犹豫纠正我；但无论如何，这解决了我的问题（多亏了

吱吱作响的ossifrage

答案）

我不确定你所说的“脆”是什么意思，但你的JSFIDLE示例在我看来非常像像素。很容易理解为什么会发生这种情况。下面是第一个

元素的

d

属性的摘录：

L944,324 L939,324 L934,325 L929,325 L924,326 L919,327 L914,327 L909,328 L904,329
L900,329 L895,330 L890,330

如您所见，坐标都有整数值，Y坐标只是间歇性地改变。结果是一条由许多水平线段组成的直线，每个线段与下一个线段之间几乎没有垂直跳跃。如果将这些坐标更改为小数点后有两位数的浮点值，则线条会更平滑

下面是一个例子：

使用CrispEdge而不是GeometricPrecision您只发布此可视化的输出，而不是生成此可视化的代码或数据。请包括其余部分。@tmcw我后来按照我所说的进行了编辑，并在理解了问题后改进了所有案例。代码库太大了，做不出什么好东西。谢谢，我给的示例代码中忘记激活插值了。但事实上，你让我想到了一些事实上导致这个问题的东西。在我的缩放中，我使用了

rangeRound（）

，这会导致缩放效果和那些小的水平/垂直线。多谢各位！我更新了我的问题，使之更适合未来的读者：）
