考虑这个使用基插值的D3JS图：

​

​

在D3JS v3中，我可以在区域上使用束插值(.interpolate("bundle").tension(0))来实现这种类型的渲染：

​

​

请注意图中的每个部分如何与其相邻部分很好地匹配。这就是我需要的。

对于D3JS v4和v5，束插值的语法现在是这样的：.curve(d3.curveBundle)。但是，现在是"intended to work with d3.line, not d3.area."

我最近从v3升级到了v5，所以我正在尝试创建一个自定义的捆绑曲线，它将与区域太一起工作，以保持我在v3中喜欢的插值类型。

我已经很接近了。这就是我到目前为止所知道的：

(捆绑包代码改编自d3形状的bundle.js。)

我非常接近:如果您检查SVG，您将看到，即使没有显示任何内容，实际上也创建了路径。

如果你看一下第一个“可见”的片段(类segment M)，你会发现它在中间的某个地方包含了一个移动命令：

代码语言：javascript
复制
M31.122194513715712,398.532825

如果我将其重命名为line命令，如下所示：

代码语言：javascript
复制
L31.122194513715712,398.532825

…那么这个片段就会显示出来。

我搞不清是自定义曲线的哪一部分造成了这种情况。我怎样才能把M变成L?

生成的路径也恰好缺少最终的Zs。我该如何处理呢？

我在D3JS中找不到太多关于自定义曲线的帮助。欢迎任何帮助。

调用areaStart和areaEnd

看起来您已经将areaStart和areaEnd函数从d3.curveBasis复制到您的自定义曲线中，该曲线主要是从d3.curveBundle绘制的。

您不能简单地将代码从d3.curveBasis复制到d3.curveBundle中，因为this引用了不同的东西。this._basis (d3.curveBasis的实例)不能访问this._line ( areaStart和areaEnd需要的变量，可以通过customBundle访问)。

您可以将this._line更改为this._basis._line，但如果您注意到，d3.curveBundle中的所有行函数都会调用它们各自的this._basis函数(例如，lineStart调用this._basis.lineStart())。如果你在这里做同样的事情，它应该是等效的：

代码语言：javascript
复制
areaStart: {
    // this._basis._line = 0; // this should work, for now
    this._basis.areaStart(); // but this makes more sense semantically
},
areaEnd: {
    // this._basis._line = NaN; // this should work, for now
    this._basis.areaEnd(); // but this makes more sense semantically
}

这样做的额外好处是，如果d3.curveBasis在未来更改其实现，这将有更高的机会兼容。

不需要new

注意，在构造函数中使用new运算符创建this._basis的新实例：

代码语言：javascript
复制
this._basis = new d3.curveBasis(context);

通过new的Basis构造函数在d3模块中内部使用，但在捆绑的库中，它是一个函数构造函数。它可以是：

代码语言：javascript
复制
this._basis = d3.curveBasis(context);

尽管使用new似乎不会破坏任何东西。有关详细信息，请参阅https://stackoverflow.com/a/9468106/6184972。

你应该使用曲线束来渲染区域吗？

正如您所注意到的，d3.curveBundle“旨在使用d3.line，而不是d3.area”。应该问问你是否应该使用curveBundle来渲染区域，因为这种省略似乎是故意的。来自https://github.com/d3/d3-shape/issues/70的@mbostock写道：

正确，d3.curveBundle仅适用于d3.line。它用于层次化的边缘捆绑，而不是渲染区域。

另请参见https://github.com/d3/d3-shape#curveBundle。

您可能应该将curveBundle与其他插值方法进行比较，看看使用它是否会以误导性的方式扭曲您的区域。

结果：

总而言之，可以在这个小提琴中看到这些变化：https://jsfiddle.net/g4ya2qso/

或者：

或者，由于其功能与d3.curveBundle非常相似，因此您可以只为.areaStart和.areaEnd添加方法，而省略所有其他自定义代码，如下所示：

代码语言：javascript
复制
var myCurveBundle = (function custom(beta) {
    function myCustomBundle(context) {
      var bundle = d3.curveBundle.beta(beta)(context);
      bundle.areaStart = function () {
        bundle._basis.areaStart();
      };
      bundle.areaEnd = function () {
        bundle._basis.areaEnd();
      };
      return bundle;
    }
    myCustomBundle.beta = function(newBeta) {
      return custom(+newBeta);
    };
    return myCustomBundle;
})(0.85);
