我想用质心位置创建几个条形图来定位它们。我已经有一个多边形的绘图代码,我想把它们组合起来。这些都是平面图,而不是世界各地的地理区域。不幸的是,我在下面的例子中有几个要点。如何使用ggplot2来覆盖我所有的点?下面是我要添加条形图的示例ggplot代码:
ggplot() + theme_minimal()+ theme(plot.title = element_text(hjust = 0.5,face="bold",size=14),line=element_line(size=0.2),
panel.grid.major = element_blank(), panel.grid.minor = element_blank(),
axis.text.x=element_blank(),axis.text.y=element_blank(),strip.text = element_text(size=11, face = "bold"),axis.title.x = element_blank(),
axis.title.y = element_blank(),legend.title=element_text(size=9, face = "bold"))+
geom_polygon(aes(x =long, y = lat, group = group), size=0.5,color="black",fill="black",alpha=0.2, data =shp1_data.frame)+
geom_polygon(aes(x =long, y = lat, group = group), size=0.5,color="white",fill="black",alpha=0.2, data =shp4_data.frame)

我放了一个数据样本
Here in my drive
使用x和y位置字段,value,变量ad location ID。绘图使用变量字段围绕每个质心(位置_i)分组。
