Manually adding legend items (guides(),override.aes) ggplot2 will not add a legend automatically unless you map aethetics (color, size etc) to a variable. There are times, though, that I want to have a legend so that it’s clear what you’re plotting. Here is the default: ...
# add title and axis text, change legend title. # 添加渐变色,并设置颜色条图例标题 scale_color_discrete(name="Cut of diamonds") print(gg1) # print the plot 如果图例显示基于因子变量的形状属性,则需要使用scale_shape_discrete(name=“legend title”)进行更改。如果它是一个连续变量,改用scale_shape...

So far, we have only used thedefault color palette of the ggplot2 package. Example 3 explains how to add user-defined colors to our plot. For this task, we have to use the scale_fill_manual function as shown below: ggplot(data, aes(x=group, y=value, fill=group))+# Manually specifi...
