我调整了@Ross的答案，得出以下时间线： 在此处输入图片描述

剩余的问题是：

  • 我无法让实习框在 2 月 12 日至 8 月 10 日之间浮动。我必须更改位置的唯一变量是text width=5cm和([yshift=-0.9cm]Y-2018-4)，对吗？
  • 我希望实习框具有与事件标签相同的圆边
  • 我希望将事件安排在发生的确切日期，而不是月初或月末。
  • 我想将灰色栏中的字体更改为默认的 Computer Modern

答案1

这不符合您的要求，因为我借用了@GuilhermeZanotelli 和@cfr 的回答：tikz 年表 年 季度 时间轴以及一些从这些来源衍生的代码，我经常使用这些代码。由于最后一个原因，这个答案中存在冗余代码，例如设置为执行某些操作但此处不需要的层。

代码：

  1. 绘制一条跨越 2 年（2017-2018 年）的时间线 (@GuilhermeZanotelli)，物理长度为 50 厘米，宽度为 2 厘米。时间线的右端需要裁剪，因为代码绘制的是完整的年份。
  2. 月份可以通过以下形式的坐标来识别Y-Year-Month(@GuilhermeZanotelli)，例如 Y-2017-1 对应 2017 年 1 月底。请注意，Y-2017-0 是 1 月初。
  3. 该命令\period在时间线上确定与指定开始和结束日期相对应的节点。period应用其第一个参数（这里是 A 和 B）给出的样式。
  4. \vevent使用命令（在@cfr 之后）定位时间线事件Chronos。其格式也由其第一个可选参数决定。垂直位置由的\vevent第二个和第三个参数给出。使用极坐标给出垂直位置很方便。它允许将事件放置在时间线的上方或下方，并将事件文本放置在其图钉的左侧或右侧。\vevent将事件放置在月初。如果需要微调位置以与事件的日期相对应，可以应用偏移，但这里没有实现。

更新

已更新以反映新要求：

  1. 计算实习节点的定位，并使用\fnode以下新命令进行定位绘制由对角坐标定义的矩形节点，文本垂直居中。格式化，包括圆角，用样式完成block。
  2. 使用部分计算将事件放置在与月份日期相对应的位置（请参阅 Tikz 手册第 4.2.1 节）。该方法假设每个月有 31 天。我用它来ifthenelse确定事件的正确位置。
  3. 从键中删除\sffamily以格式化周期标签。
