How To Rotate x-axis Text Labels in ggplot2 How to rotate x-axis text labels 45 degree? Note that rotating axis text labels are not always the best solution. In most cases we can use coord_flip() to switch and and y-axis and make the axis text easy to read. And with ggplot2 version 3.3.0, we can avoid overlapping label texts by moving the labels along y-axis alternatively.

ggplot2 axis scales and transformations - Easy Guides - STHDA This R tutorial describes how to modify x and y axis limits (minimum and maximum values) using ggplot2 package. Axis transformations (log scale, sqrt, …) and date axis are also covered in this article. ... name: x or y axis labels; breaks: to control the breaks in the guide (axis ticks, grid lines, …). Among the possible values, there are : How to Add Dollar Sign for Axis Labels with ggplot2? df %>% ggplot(aes(x=Education, y=Salary)) + geom_col() In the barplot, height of bars represent salary for each education category. Note that on y-axis we have the salary as numbers. Instead, sometimes you would like to have the y-axis with dollars. We can use the R Package scales to format with dollar symbol. How to change the Y-axis title to horizontal using ggplot2 in R? The default direction of Y-axis title using ggplot2 in R is vertical and we can change to horizontal. For this purpose, we can use theme function of ggplot2 package. We would need to use the argument of theme function as axis.title.y=element_text (angle=0)) and this will write the Y-axis title to horizontal but the position will be changed to top.

How to Add Labels Directly in ggplot2 in R - GeeksforGeeks Method 1: Using geom_text () This method is used to add Text labels to data points in ggplot2 plots.

Dual Y axis with R and ggplot2 - the R Graph Gallery We'll see a trick below in the tweaking section. # Start with a usual ggplot2 call: ggplot (data, aes ( x= day, y= temperature)) + # Custom the Y scales: scale_y_continuous ( # Features of the first axis name = "First Axis", # Add a second axis and specify its features sec.axis = sec_axis ( trans=~. *10, name="Second Axis") ) + theme_ipsum () Chapter 4 Labels | Data Visualization with ggplot2 Y axis label ggplot(mtcars) + geom_point(aes(disp, mpg)) + labs(title = 'Displacement vs Mileage', subtitle = 'disp vs mpg', x = 'Displacement', y = 'Miles Per Gallon') 4.6 Axis Range In certain scenarios, you may want to modify the range of the axis. In ggplot2, we can achieve this using: xlim () ylim () expand_limits ()

Adding Labels to a {ggplot2} Bar Chart - Thomas' adventuRe Let's move the labels a bit further away from the bars by setting hjust to a negative number and increase the axis limits to improve the legibility of the label of the top most bar. chart + geom_text ( aes ( label = pct, hjust = -0.2 )) + ylim ( NA, 100) Copy. Alternatively, you may want to have the labels inside the bars. Add Labels at Ends of Lines in ggplot2 Line Plot in R (Example) ggplot ( data_label, aes ( x, y, col = group)) + # Draw ggplot2 plot with labels geom_line () + geom_label_repel ( aes ( label = label) , nudge_x = 1 , na.rm = TRUE) + theme ( legend.position = "none") Figure 2 shows the output of the previous code: A ggplot2 line plot with labels at the ends of lines.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.
