Discrete Value Bar graphIn ggplot2, the default is to use stat_bin, so that the bar height represents the count of cases.Bar graphs of valuesHere is some sample data (derived from the tips dataset in the reshape

We also need to install and load the ggplot2 package, if we want to use the functions that are contained in the package:install.packages("ggplot2") # Install & load ggplot2 package library("ggplot2")Next, we can draw a graph of our example data:...
As a next step, we can draw our data in a barplot: ggp1<-ggplot(data)+# Draw ggplot2 barplotgeom_bar(aes(group, sample), stat="identity")ggp1 By executing the previous code we have plotted Figure 1, i.e. a ggplot2 bargraph without any lines or secondary y-axes. ...
ThisR tutorialdescribes how to createline plotsusingR softwareandggplot2package. In a line graph, observations are ordered by x value and connected. The functionsgeom_line(),geom_step(), orgeom_path()can be used. x value (for x axis) can be : ...
In base R, theline functionallows to build quality line charts. Dual Y axis withggplot2 Warning: a dual Y axis line chart represents the evolution of 2 series, each plotted according to its own Y scale. This kind of chartmustbe avoided, since playing with Y axis limits can lead to com...
Mind the Spaghetti (ggplot2)When too many groups are displayed on the same line chart it gets very hard to get insight from the figure. This is commonly called a spaghetti chart. Here are a few alternatives using ggplot2: annotation and small multiple. ...
Basic line chart withggplot2andgeom_line() Aline chartorline graphdisplays the evolution of one or several numeric variables. Data points are usually connected by straight line segments. You read an extensive definitionhere. The input data frame requires at least 2 columns: ...
ggplot(df, aes(x = temp, y = enzyme_activity)) + geom_line() Output: 2. Multiple Lines in Line Graph R Code: library(ggplot2) temp = c(4, 25, 50, 85, 100) enzyme_one_activity = c(0.543, 0.788, 0.800, 0.898, 0.882)
