ggplot2natively supports several methods to customize the color palette: p <- ggplot(iris, aes(x=Sepal.Length, y=Sepal.Width, color=Species)) + geom_point(size=6) p + scale_color_brewer(palette = "PuOr") See all Paletteer: The Definitive Catalog of R Color Palettes ...

p1_npg <- p1 + scale_color_npg() p2_npg <- p2 + scale_fill_npg() grid.arrange(p1_npg, p2_npg, ncol = 2) Non-ggplot2 graphics To apply the color palettes in ggsci to other graphics systems (such as base graphics and lattice graphics), simply use the palette generator functions i...
ggplot(mtcars) + geom_bar(aes(factor(hp), fill=factor(hp))) + scale_fill_brewer(palette="Set2") 的确, length(unique(mtcars$hp)) 有 22 个唯一值,然而调色板 Set2 只有 8 中颜色。调色板中的颜色缺乏导致了ggplot如下的警告: Warning message: In RColorBrewer::brewer.pal(n, pal) : n too...
my_palette <- colorRampPalette(c("red", "blue")) 接下来,使用ggplot函数创建一个绘图对象,并指定数据源和绘图要素。例如,我们可以使用以下代码创建一个简单的散点图: 代码语言:txt 复制 library(ggplot2) data <- data.frame(x = 1:10, y = 1:10, group = rep(c("A", "B"), each =...
Two color scale functions are available in ggplot2 for using the rcolorbrewer palettes: scale_fill_brewer()for box plot, bar plot, violin plot, dot plot, etc scale_color_brewer()for lines and points # Box plotbp + scale_fill_brewer(palette ="Dark2")# Scatter plotsp + scale_color_bre...

结果仍然是一个ggplot对象,这意味着您可以通过使用传统的ggplot2代码添加层来继续定制它。 ggblanket由David Hodge编写,可在CRAN上下载。 其他几个包也尝试简化ggplot2并更改其默认值,包括ggcharts。它的简化函数使用语法 library(ggcharts) column_chart(snowfall2000s, x =Winter, y =Total) ...
Example 1: Drawing ggplot2 Barplot with Default Colors The following syntax shows how to create a barchart with a different color for each of the bars using the default ggplot2 color palette. For this, we have to specify the fill argument within the aes function to be equal to the groupin...
