Gradient colors for histogram plots Gradient between n colors Infos The goal of this article is to describe how to change the color of a graph generated using R software and ggplot2 package. A color can be specified either by name (e.g.: “red”) or by hexadecimal code (e.g. : “#...
This example shows how to create a venn diagram with two sets using the ggvenn function provided by the ggvenn package. For this, we simply have to specify the name of our list and the element names in our list that we want to draw: ...
Thedataparameter enables you to specify the dataframe that contains the variable you want to plot. Remember that ggplot2 is set up to visualize data that’s in dataframes, so you need to provide the name of a dataframe as the argument to this parameter. For example, if you have a datase...
Converting it topolar coordinate systemto make it round. Adding data labels and colors - supplied as hex codes. Adding the title, removing axis labels, and removing a lot of the default theme. There are a wide range of additional properties that can be modified in theggplot2package including...
Thank you for the positive comment, highly appreciated! Here’s how I’ll add a legend: I specify the variable color in aes() and give it the name I want to be displayed in the legend. library(ggplot2) theme_set(theme_minimal()) data(economics) ggplot(economics, aes(x = date)) +...
How to apply paletteR in ggplot2 Applying the obtained palette in ggplot is actually easy. The object you obtain from the _create_palette_ function is a vector of hex codes (another way of codify colours, more on the Wikipedia page). You therefore have to pass it to your ggplot plot em...
sizevector from that data frame as the plotting aesthetic. The second line tells ggplot to make a histogram out of the given data withgeom_histogram, and we specify a binwidth of 1 so that each column represents one discrete value of listicle. Running that code will cause a plot to pop...
Use Data Frame Row Indices as X in ggplot2 Plot in R (Example Code) Modify Number of Decimals on Axis Tick Labels of ggplot2 Plot in R (Example Code) Append Empty Row (NA Values) to Bottom of Data Frame in R (Example Code) Specify Different Group Colors in ggplot2 Graphics in R ...
Theyparameter allows you to specify the y axis coordinates of the points along the line you want to draw. Here’s a very simple example. The following line has been created by connecting four points. The y axis coordinates of these points are at2,5,4, and8. ...
