library(plotly) p <- ggplot(economics, aes(unemploy, date)) + geom_line(orientation = "y") plotly::ggplotly(p) Step plot geom_step() is useful when you want to highlight exactly when the y value changes. Defaul
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 reshape2 package):dat<-data.frame(time=factor(c...
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:...
Note: All the line graphs plotted above were through the function plot(). However, there are other libraries/functions also available which help us draw the line graph. One such library is “ggplot2”. GGplot2 Library below is the ggplot2 library which helps to draw line graph in R are ...
Dual Y axis with ggplot2Warning: a dual Y axis line chart represents the evolution of 2 series, each plotted according to its own Y scale. This kind of chart must be avoided, since playing with Y axis limits can lead to completely different conclusions. Visit data-to-viz for more info....
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...
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. ...
This R graphics tutorial describes how to change line types in R for plots created using either the R base plotting functions or the ggplot2 package.
# Change line size ggplot(data=economics, aes(x=date, y=pop, size=unemploy/pop))+ geom_line() Line graph with error bars The function below will be used to calculate the mean and the standard deviation, for the variable of interest, in each group : ...
brewerPaletteThis can be also used to indicate group colors. In this case the parameter groupColors should be NULL. e.g: brewerPalette=“Paired”. ….Other arguments passed on to ggplot2.customize custom function or to geom_line functions from ggplot2 package. ...
