我正在尝试按如下方式构建堆栈条形图：

ggplot(x, aes(Date, count, group=Region)) + 
   geom_bar(aes(fill=Type, width=0.3),stat="identity", position="stack") + 
   scale_x_date(breaks = "1 month", 
                minor_breaks = "2 weeks", 
                labels=date_format("%b-%y")) +
   geom_smooth(method="lm", se=T, size=0.5, colour="yellow") +
   facet_wrap(~Region)

默认情况下，我看到一些缺失点但是当我拉伸绘图窗口时，会出现点。我真的需要图表中的所有点，否则看起来我很想报告数据。任何建议如何解决这个问题，以便我看到图表上的所有数据点。我的窗口大小是500乘500。

实际上，通过增加屏幕尺寸，会出现更多条形图。您无法在R控制台的小窗口中看到它们，因为条的宽度太小。但是当你保存它时，可以在输出中看到条形图：

plot <- ggplot(x, aes(Date, count, group=Region)) + 
geom_bar(aes(fill=Type, width=0.3),stat="identity", position="stack") + 
scale_x_date(breaks = "1 month", 
            minor_breaks = "2 weeks") +
geom_smooth(method="lm", se=T, size=0.5, colour="yellow") +
facet_wrap(~Region)

ggsave("test.pdf",plot )

要查看R控制台中的所有点，请增加宽度，例如：

(plot <- ggplot(x, aes(Date, count, group=Region)) + 
geom_bar(aes(fill=Type, width=1),stat="identity", position="stack") + 
scale_x_date(breaks = "1 month", 
            minor_breaks = "2 weeks") +
geom_smooth(method="lm", se=T, size=0.5, colour="yellow") +
facet_wrap(~Region))

ggplot2窗口中没有显示某些数据
