How do I make a graph with ggplot2?
Apr 06, 2020 · chart + geom_text ( aes ( label = pct, hjust = -0.2 )) + ylim ( NA, 100) Copy. Alternatively, you may want to have the labels inside the bars. chart + geom_text ( aes ( label = pct, hjust = 1 )) Copy. Again, a bit close to the end of the bars. By increasing the hjust value the labels can be moved further to the left.
How to manually fill a ggplot2 with different colors?
Jun 06, 2021 · Different fill color. Use the command fill to add color inside the bars. Since, the bars are in different x-axis values we need to assign the x-axis variable to the fill. In our case, match is in the x-axis, so we write fill=match. You need to write this command inside the aes () also known as the quoting function or aesthetic function under ...
How do I use stat in ggplot?
Adding labels/markers to a bar graph will help you interpret the graph correctly. You can label each bar with the actual value by incorporating geom_text (). # Add labels above bars ggplot (survey, aes (x=fruit, y=people, fill=fruit)) + geom_bar (stat="identity") + geom_text (aes (label=people), vjust=-0.3, size=3.5)
How do you label a bar graph in R?

How do you label a bar graph?

How do I change the order of bars in a bar chart in R?
The reorder function is used here to change the order of the graphs. Here if you want ascending order then you'll use '+' plus sign, if you want in descending order then you should use '-' minus sign. Note: Column2 must be the column with numeric data. Example: Let us first show the same bar plot in ascending order.Jun 29, 2021
How do you name a graph?
The proper form for a graph title is "y-axis variable vs. x-axis variable." For example, if you were comparing the the amount of fertilizer to how much a plant grew, the amount of fertilizer would be the independent, or x-axis variable and the growth would be the dependent, or y-axis variable.Apr 25, 2018

How do you arrange a graph in descending order in R?
To sort a data frame in R, use the order( ) function. By default, sorting is ASCENDING. Prepend the sorting variable by a minus sign to indicate DESCENDING order.
How do you arrange a bar chart in descending order in Python?
To create barplot with bars ordered in descending order, we first sort the dataframe such that it is ordered in descending order. To sort the Pandas dataframe, we need to use ascending=False argument with Pandas sort_values() function. We get dataframe ordered in descending order.Feb 10, 2020

You can download this post as a PDF or RMarkdown file. These formats support code highlighting.
Motivation
There is a wealth of information on the philosophy of ggplot2, how to get started with ggplot2, and how to customize the smallest elements of a graphic using ggplot2 — but it's all in different corners of the Internet. It can be difficult for a beginner to tie all this information together.
Data
We will be using the GapMinder dataset that comes pre-packaged with R. This dataset is an excerpt from the GapMinder data, and it shows the life expectancy, population and GDP per capita of various countries over 12 years between 1952 to 2007.
Visualization task
We would like to show the change in life expectancy from 1952 to 2007 for 11 (arbitrarily-selected) countries: Bolivia, China, Ethiopia, Guatemala, Haiti, India, Kenya, Pakistan, Sri Lanka, Tanzania, Uganda.
Components of the graph
ggplot2 is based on the "grammar of graphics", which provides a standard way to describe the components of a graph (the "gg" in ggplot2 refers to the grammar of graphics). It has specialized terminology to refer to the elements of a graph, and I'll introduce and explain new terms as we encounter them.
Revisiting ggplot () graph components
Now that we understand how to build a ggplot, let’s map the elements of our graph to the components of a plot:
Basic graphs with discrete x-axis
With bar graphs, there are two different things that the heights of bars commonly represent:
With a numeric x-axis
When the variable on the x-axis is numeric, it is sometimes useful to treat it as continuous, and sometimes useful to treat it as categorical. In this data set, the dose is a numeric variable with values 0.5, 1.0, and 2.0. It might be useful to treat these values as equal categories when making a graph.

Next Steps
- You can make the following graphs to learn more about ggplot(): 1. Change the font and font size for the chart title, facet labels, and axis labels (you’ll need to use the theme()function) 2. Modify the existing graph to show the value of life expectancy for each bar (you’ll need to add a geom_text()) 3. Create some dummy data with confidence inter...
