ggplot 更改图例中的几何顺序 [英] ggplot change geom order in legend

问题描述

我有两个堆积面积图，顶部绘制了一条线.在这两种情况下，我的绘图顺序都是这样的:

I have two stacked area plots with a line plotted on top. In both cases, my plotting order has been this:

1. 创建 ggplot
2. 添加堆叠区域(geom_area)；更改堆叠区域颜色
3. 添加行(geom_line)；更改线条颜色

1. Create ggplot
2. Add stacked area (geom_area); change stacked area colors
3. Add line (geom_line); change line color

在我的第一个图表中，堆积区域颜色显示在我的图例报告捕获线上方，而在我的第二个图表中，报告捕获线显示在​​堆积区域颜色上方.两者在 R 代码方面似乎没有太大区别，所以我不知道为什么它们在图例顺序上不同.

In my first graph, the stacked area colors show up above the Reported Catch line my legend, while in my second graph, the Reported Catch line shows up above the stacked area colors. There appears to be no major difference between the two in terms of R code, so I have no idea why are they different in legend order.

如何更改第一个图形的图例以匹配第二个图形的图例，以便Reported Catch"线位于堆叠区域颜色上方?

How can I change my first graph's legend to match the second graph's legend, so that the "Reported Catch" line is above the stacked area colors?

图 1.图例顺序不正确.

Plot 1. Incorrect legend order.

绘图 2.正确的图例顺序.

Plot 2. Correct legend order.

推荐答案

guides(fill = guide_legend(reverse = TRUE) 应该可以工作！
