ggplot2 - 在对数刻度中强制10 ^ 0

Question

我正在尝试将值'10 ^ 0'和'10 ^ 7'添加到下图中。但是，我似乎无法获得图表中显示的任何值。任何帮助将不胜感激。

我正在使用的缩放功能是

    scale_y_log10(breaks = trans_breaks("log10", function(x) 10^x),
               labels = trans_format("log10", math_format(10^.x)))

完整代码位于图片下方。

ggplot(data=mydata.long, aes(x=variable, y=value, group=BenchMark, shape=BenchMark, colour=BenchMark)) + 
    geom_line(aes(linetype=BenchMark), size=1) +     # Set linetype by sex
    geom_point(size=3, fill="white") +         # Use larger points, fill with white
    scale_colour_hue(name="BenchMark",      # Set legend title
                     l=30)  +                  # Use darker colors (lightness=30)
    scale_shape_manual(name="BenchMark",
                       values=c("#CC0000", "#006600", "#669999", "#00CCCC", 
                             "#660099", "#CC0066", "#FF9999", "#FF9900", 
                             "black", "black", "black", "black", "black")) +      # Use points with a fill color
    scale_linetype_discrete(name="BenchMark") +
    xlab("Pipeline stage") + ylab("Number of comparisons") + # Set axis labels
    ggtitle("The number of tests identified\n at each pipeline stage\n in a two stage pipeline") +     # Set title
    theme_bw() +       # Position legend inside
    scale_y_log10(breaks = trans_breaks("log10", function(x) 10^x),
                   labels = trans_format("log10", math_format(10^.x)))

Answer 1

您可以执行以下操作：

scale_y_log10(limits=c(10^0, 10^7), breaks=10^(0:7))
