我正在尝试生成一个水平图，在轴上标记有刻度。

df = data.frame(quality = c("low", "medium", "high", "perfect"),
                n = c(0.1, 11, 0.32, 87.45))

require(ggplot2)

                  position = position_dodge(width = 0.9),
                  hjust = -0.2,
                  size = 10, color = "gray50") +
        coord_flip() +
        ggtitle("") +
        xlab("gps_quality\n") +
        #scale_x_continuous(limits = c(0, 101)) +
        theme_classic() +
        theme(axis.title …
