In the R code below, barplot fill colors are automatically controlled by the levels of dose: # Change barplot fill colors by groups p-ggplot(df, aes(x=dose, y=len, fill=dose)) + geom_bar(stat="identity")+theme_minimal() p It is also possible to change manually barplot fill colors using the functions : scale_fill_manual(): to use custom colors It would be easier to do it with some mock data, but when you work in real world, you also have real-world problems. 简单柱状图 ggplot() + geom_bar(data = mpg, aes(x = class), stat = "count") Let's start of with a simple chart, showing the number of customers per year: ggplot2 works in layers.

The color aesthetic is used by geom_point and geom_smooth.Three different regression lines are now drawn. La idea es contar las cantidades por cada factor y realizar un barplot combinado para poder ver los niveles Q1 apilados y así compararlos. In a percent stacked barplot the percentage of each subgroup is represented instead of count or y … if TRUE then percentages are computed separately for each value of x (i.e., conditional percentages of by within levels of x); if FALSE then total percentages are graphed; ignored if scale="frequency". We will first start with adding a single regression to the whole data first to a scatter plot. In many cases new users are not aware that default groups have been created, and are surprised when seeing unexpected plots.
