我不喜欢在以下位置获得的默认调色板：我有一个类似的问题-我想使用viridis调色板给边缘着色-我用Symboli...
如果数据是因子型的颜色映射,颜色标尺则是离散型的,修改标尺需要使用相应的离散型颜色标尺如scale_color_discrete或scale_color_hue。这两个函数只是别名函数,早期版本只有scale_color_hue。它们通过设置色调范围(h)、饱和度(c)和亮 度(l)获取颜色,不太容易掌握: ...
[21] "scale_fill_viridis_c" "scale_fill_viridis_d 先看看“continuous”的用法。对于数据为非因子型的填充色映射,ggplot2自动使用“continuous”类型颜色标尺表示连续颜色空间。如果要修改默认颜色就要使用scale_fill_continuous函数进行修改,这个函数最有用的参数是low和hig...
There doesn't appear to be any way to tell ggplot these fill values are expected in order to suppress the warnings. The closest I can see is something likescale_fill_viridis_c(na.value = "transparent", trans = "log"), which plots fine since apparently -Inf, NaN, and NA are treated...
Scales map a dimension of abstract data to a visual representation. Although most often used for encoding data as position, say to map time and temperature to a horizontal and vertical position in a scatterplot, scales can represent virtually any visual encoding, such as color, stroke width, ...
