javascript - d3.time.format.multi 不是函数

标签 javascript d3.js dataset stream-graph

我需要使用 d3.js 设计流图，我开始试验 GitHub 上托管的代码.由于我的数据集预计在日期的最小值和最大值之间有不同的范围(可以是一个月或几年的时间)，我决定对我的 x 轴上的刻度使用多尺度格式而不是将格式和间隔固定为周、月、年等。例如，如果我按照 GitHub 上示例代码中给出的相同方式保留刻度格式

var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom")
.ticks(d3.time.weeks);

如果我的数据集中的日期范围跨越数年，则 x 轴的图例会变得拥挤且不可读。

我尝试使用多尺度格式，但无法绘制可视化效果，浏览器的 Dev 工具返回以下错误:

d3.time.format.multi is not a function

我真诚地希望有人能建议我解决这个问题。

下面你可以看到我的完整代码:

最佳答案

您的代码使用的是 d3 版本 2。请尝试使用第三个版本:
