Stacked bar chart

阅读更多关于 Stacked bar chart

I would like to create a stacked chart using ggplot2 and geom_bar. Here is my source data: Rank F1 F2 F3 1 500 250 50 2 400 100 30 3 300 155 100 4 200 90 10 I want a stacked chart where x is the rank and y is the values in F1, F2, F3. # Getting Source Data sample.data <- read.csv('sample.data.csv') # Plot Chart c <- ggplot(sample.data, aes(x = sample.data$Rank, y = sample.data$F1)) c + geom_bar(stat = "identity") This is as far as i can get. I'm not sure of how I can stack the rest of the field values. Maybe my data.frame is not in a good format? You said : Maybe my data.frame is not in a good

Generate paired stacked bar charts in ggplot (using position_dodge only on some variables)

阅读更多关于 Generate paired stacked bar charts in ggplot (using position_dodge only on some variables)

问题 I\'m hoping to use ggplot2 to generate a set of stacked bars in pairs, much like this: With the following example data: df <- expand.grid(name = c(\"oak\",\"birch\",\"cedar\"), sample = c(\"one\",\"two\"), type = c(\"sapling\",\"adult\",\"dead\")) df$count <- sample(5:200, size = nrow(df), replace = T) I would want the x-axis to represent the name of the tree, with two bars per tree species: one bar for sample one and one bar for sample two. Then the colors of each bar should be determined by

ggplot bar plot with facet-dependent order of categories

问题 I\'ve seen many questions (often linked to Order Bars in ggplot2 bar graph) about how to (re)order categories in a bar plot. What I am after is just a touch different, but I haven\'t found a good way to do it: I have a multi-faceted bar plot, and I want to order the x axis for each facet independently, according to another variable (in my case, that variable is just the y value itself, i.e. I just want the bars to go in increasing length in each facet). Simple example, following e.g. Order
