我正在尝试水平制作以下图表，我使用了以下回答作为基础：
输入：

输出：
我知道它看起来并不像我想要的那样，例如日期非常粗糙，我希望它们更明显（更流畅）。我会继续尝试，任何更新我都会在这里发布。任何帮助我都会非常感激。
答案1
我添加mark=between positions #1 and 0.99 step 1.5em with {\arrow{>} [scale=0.5]}了你的decoration，所以原始源代码可以像以前一样工作，
我也在index = -2上创建了你的设计doubleSaddle，名字不太好。我用颜色画出来，这样更容易理解线条是如何control ..在保持流向的同时镜像的。我用了蒂克泽特通过使用鼠标移动节点和控件来绘制它。
您的和的代码index=0与index=1您原来的手绘不同。我没有改变它们，我保留了您在代码中写的数字。
其他指标我只是flow=<parameter>为了得到更好的结果而修改了一下。
