To do this, we have to use the scale_fill_manual function of the ggplot2 package. Within this function, we need to specify a color for each of the bars as shown below:ggplot(data, aes(x, y, fill = x)) + # Manually specifying colors geom_bar(stat = "identity") + scale_fill_...
同样地,我们可以手动设置轮廓的颜色。只需将上述代码中的关键词 fill 到处替换为 color 。现在该函数将变成: scale_color_manual( )灰度 这里使用的函数是scale_fill_grey( )。由于我们需要不同的灰度颜色,所以填充在 aes( )里面。最后调用函数scale_fill_grey( )。
