我使用以下代码制作了一个带有集成geom_line的散点图进行比较:
ggplot() +
geom_text_repel(data=MovieData, direction = "y", hjust= 0.5,
aes(x=Year, y=Income, color=Genre,label=MovieData$Movie)) +
geom_point(data=MovieData, size=3, aes(x=Year, y=Income, color=Genre)) +
scale_color_brewer(palette = "Set1") +
theme_minimal() +
ylab("Income (Miillion EGP)") +
scale_x_continuous(labels=c("1998","2003","2008","2013","2018")) +
ggtitle("Movie income and genre by year") +
geom_line(data=AhmadHelmyMovies, size= 1.5 , color= "dodgerblue3", alpha=0.5,
aes(Year,Income)) +
geom_point(data=AhmadHelmyMovies, size= 5,
aes(Year,Income, pch="Ahmad Helmy Trend"), color="red") +
geom_line(data=ElsaqqaMovies, size= 1.5 , color= "red3", alpha=0.5,
aes(Year,Income)) +
geom_point(data=ElsaqqaMovies, size= 5 ,
aes(Year,Income, pch="Ahmad Elsaqqa Trend"), color="blue")
现在我对此图有多个问题:
a。首先,传说似乎与多个形状重叠红色圆圈
b。其次,与形状(pch
参数)相关的图例以错误的方式上色,我为形状分配了颜色,并希望它们与图例匹配
c。有什么建议可以改善图表吗?
现在我仅在最近的两周内学习了R,所以请对我轻松理解术语和代码,并为我进行解释。提前致谢。
