我研究这个特殊的堆积面积图已有一段时间了。我是 d3 的新手，所以我需要一些关于放置什么的指针，以便 d3 获得正确的信息。

最佳答案

输入数据不正确:

Note that each series must have the same number of values per series, and each value must have the same x-coordinate; if you have missing data or inconsistent x-coordinates per series, you must resample and interpolate your data before computing the stacked layout.
