This function is from easyGgplot2 package. R Stacked Bar Percentage of Total. Bar plots represent the categorical data in rectangular manner. For example, we may want to visualize the total popcorn and soda sales for three different sports stadiums. ggplot stacked bar plot - how to apply different length color ramps to each bar? But ggplot() really shines when you have a lot of data. Below mentioned two plots provide the same information but through different visual objects. Creating a plot with ggplot2 starts with the ggplot() function. It follows those steps: always start by calling the ggplot() function. Python has a number of powerful plotting libraries to choose from.
