这里是我的数据结构:geom_area不堆叠(ggplot)
Classes ‘tbl_df’, ‘tbl’ and 'data.frame': 60 obs. of 3 variables:
$ year : num 1990 1990 1991 1992 1993 ...
$ studyType: Factor w/ 4 levels "meta","observational",..: 2 3 3 1 3 3 3 1 3 3 ...
$ N : int 1 4 4 1 2 5 3 1 2 6 ...
我尝试使用下面的代码进入一个堆叠面积图这样的:
ggplot(evidence.summary.main, aes(x = year, y = N, fill=studyType)) +
geom_area(alpha=.80)
任何想法为什么我无法正确堆叠这个?
而且我的数据从dput
:
structure(list(year = c(1990, 1990, 1991, 1992, 1993, 1994, 1995,
1996, 1996, 1997, 1997, 1998, 1998, 1999, 1999, 2000, 2000, 2000,

你可以输入你的数据框吗? –
这可能是因为你缺少一些数据。例如,在某些年份,您缺少“观察”数据(可能对其他一些studyType也是如此,我没有检查100%)。如果你用缺失的数据填充你的数据框(例如设置为0),它可能会有所帮助。 – untitled
