山脊图介绍

山脊图（Ridge Plot），也被称为Joy Plot，是一种用于可视化数据分布的图表，特别是用于显示多个组的分布情况。在这种图表中，每个组的数据分布都通过平滑的密度曲线来表示，这些曲线沿着垂直轴堆叠，形成类似山脊的视觉效果。山脊图是核密度估计（KDE）的一个应用，它提供了比传统的条形图或直方图更平滑的数据分布视图。

用途：山脊图主要用于展示和比较不同组或类别内数据的分布情况。它特别适合于以下情境：

比较多个分布：当需要展示和比较多组数据的分布形状时，山脊图能够直观地展示出分布之间的差异。
展现趋势变化：在时间序列数据中，山脊图可以用来展示数据随时间的变化趋势。
优化空间利用：通过堆叠的方式，山脊图能在有限的空间内展示大量的分布信息。

缺点：

可读性：对于不熟悉这种图表的观众来说，山脊图可能难以理解和解读。
叠加问题：当曲线重叠较多时，可能会导致图表的某些部分难以区分。
数据量限制：对于数据量非常大的数据集，山脊图可能不那么有效，因为过多的曲线会使图表变得杂乱。

应用场景：

时间序列分析：在金融、经济、气象等领域，用于展示某个变量随时间的变化趋势。
社会科学：比如在选举数据分析中，展示不同候选人或党派在不同地区或人群中的支持率分布。
生物医学：用于展示不同实验组或治疗方法下的生物统计数据分布。
