Question

我的问题是this one的扩展但我在我的ggplot中使用了2个stat_summary调用。第一个stat_summary显示每个单位的平均值，第二个stat_summary显示多个单位的组（时间）的总体平均值（参见附图）。使用color = factor（unit）并使用scale_colour_manual（）指定，分配第一个stat_summary的颜色没有问题。我想在第二个stat_summary中通过2个时间级别（pre和pst）分配颜色，例如color = time，但我不能再使用scale_colour_manual来指定颜色。我试过了： color = c（＆＃34; red＆＃34;，＆＃34; blue＆＃34;），颜色= cbPalette2， aes（color = paste（＆＃34; mean＆＃34;，time）））（如相关问题所示），但没有运气。任何帮助将不胜感激。

数据：

正如我在评论中指出的那样，我不确定您希望绘图的样子，但是您可以通过使用填充标记（例如形状21 - 25）为一个geom和非ge来获得单独的颜色映射填充另一个标记。然后，您可以将变量映射到填充标记的填充美学，并将另一个变量映射到非填充标记的颜色美学。

以下是使用修改后的代码版本的示例。这可能不是你想到的那样，所以让我知道你实际上想要做什么，并且我将根据需要进行修改。

pd = position_dodge(0.75)

ggplot(stack, aes(x=tied, y=measure)) + 
  geom_point(size=1, aes(fill=time), shape=21, colour=NA, 
             position=position_jitterdodge(jitter.width=NULL, jitter.height=0, dodge.width=0.75)) +
  stat_summary(shape=95, fun.y=mean, geom="point", size=12, position=pd) +
  stat_summary(shape=95, aes(colour=factor(unit)), fun.y=mean, geom="point", size=8, position=pd) +
  facet_grid(.~rep) +
  labs(fill="Time", x="tied", y="measure (cP)") +
  # scale_fill_manual(values=cbPalette2) +
  # scale_colour_manual(values=unitcolours1) +
  guides(colour=FALSE) +
  #scale_shape_identity() +
  theme_bw() +
  scale_y_continuous(limits=c(-0.1,1.24), breaks=seq(0, 1.2, 0.1))
