绘制折线图时,我对x轴有问题。如下图所示,我的标签太多了。ggplot2中的缩放x轴
我尝试只包括使用seq()
一些标签来补救方案,但我会遇到这样的错误:
ggplot(df, aes(x = date, y = measure, group = 1)) +
geom_line() +
theme_bw() +
theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5)) +
xlab("X-Axis") +
ylab("Y-Axis") +
scale_x_continuous(breaks = round(seq(min(df$date), max(df$date), by = 221.2), 1))
#> Error in seq.default(min(df$date), max(df$date), :
#> 'from' must be a finite number
#> In addition: Warning message:
#> In seq.default(min(df$date), max(df$date), :
#> NAs introduced by coercion
有什么建议?如果有帮助,df$date
被认为是一个角色。也许,我应该将其转换为数字或作为日期时间?
请提供用于生产该地块您'df' – useR
