带有彩条的自定义图形

Question

我想用颜色条重新创建下图。

来源：https://dl.acm.org/citation.cfm?id=1531403

我尝试使用带有颜色条的 pgfplots 轴环境，并设法使颜色条正确。但我不知道如何获得彩色图。

到目前为止，我已经做到了这一点：

我有以下问题：

1. 如何将颜色条移动到方格网格的右侧？
2. 如何绘制每个方块内的彩色线图？

Answer 1

一般来说，如果你将问题分成几个较小的部分，你会得到更多的关注，因为其他人恰好想要制作这张图表的可能性可能不会太大。

1. 为了生成这种子图布局，我使用了该groupplots库。
2. 颜色条是独立制作的，并通过保存箱插入，以避免嵌套tikzpicture。
3. 为了简化问题，各种情节以循环方式产生。
