Rename x y label on plot in r2/3/2024 # change the styling of both the axis simultaneously from this-Īxis. How to Change X-Axis Labels in ggplot2 You can use the scalexdiscrete () function to change the x-axis labels on a plot in ggplot2: p + scalexdiscrete (labelsc label1, label2, label3. Can I use a function to rename x axis labels in r Yes, you can use a function to rename x axis labels in r. You can also use the labels argument to specify the labels for the x and y axes. ![]() This function will allow you to specify the labels for the x and y axes. Plot.title = element_text(color="Blue", size=30, hjust = 0.5), In order to change the x axis labels in R, you will need to use the axis function. Scale_size_area() + ggtitle("Weighted Scatterplot of Watershed Area vs. Mygraph<-p + geom_point(aes(size= nitrogen)) + ![]() P <- ggplot(ex1221new, aes(discharge, area), main="Point") Mygraph$labels$y="Area Affected" # changes y axis titleĪnd the work is done. 8.4 Changing the Order of Items on a Categorical Axis 8.5 Setting the Scaling Ratio of the X- and Y-Axes 8.6 Setting the Positions of Tick Marks 8.7 Removing Tick Marks and Labels 8.8 Changing the Text of Tick Labels 8.9 Changing the Appearance of Tick Labels 8.10 Changing the Text of Axis Labels 8. In my answer,I have stored the plot in mygraph variable and then I have used mygraph$labels$x="Discharge of materials" #changes x axis title In that window the size of the Plot pane is just too narrow to allow R to reasonably place the extra labels under the x-axis. Also, the question which was asked has few changes in codes like then ggplot package has deprecated the use of "scale_area()" and nows uses scale_size_area() Since the data ex1221new was not given, so I have created a dummy data and added it to a data frame. Which gives an identical figure to the one above. Draw a scatter plot with decorations such as axes and titles in the active graphics window. Title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")Īn alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function ggplot(ex1221, aes(Discharge, Area)) + tag can be used for adding identification tags to differentiate between multiple plots. It's common to use the caption to provide information about the data source. Use the plot title and subtitle to explain the main findings. Always ensure the axis and legend labels display the full variable name. In this article, I’ll illustrate how to rename the x-axis labels of a boxplot in the R programming language. Ggtitle("Weighted Scatterplot of Watershed Area vs. Good labels are critical for making your plots accessible to a wider audience. You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call. One advantage is that ggplot works with ames directly. Also, you don't need (and shouldn't) pull columns out to send to ggplot. This results in different appearances, as shown below.Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Discharge and Nitrogen Levels (PPM)') which gives an identical figure to the one above. With a coordinate transform, the transformation happens after the breaks and scale range are decided. ggplot (ex1221, aes (Discharge, Area)) + geompoint (aes (sizeNO3)) + scalesizearea () + labs (size 'Nitrogen', x 'My x label', y 'My y label', title 'Weighted Scatterplot of Watershed Area vs. With a scale transform, the data is transformed before properties such as breaks (the tick locations) and range of the axis are decided. One is to use a scale transform, and the other is to use a coordinate transform. norescale specifies that the ticks or labels in the option be placed directly on the graph without rescaling the axis or associated plot region for the new. There are two ways of transforming an axis. It is possible to transform the axes with log, power, roots, and so on. As you can see, the title labels are named x and y. # The scale will show only the ones that are within range (3.50-6.25 in this case)īp + scale_y_continuous ( breaks = seq ( 1, 10, 1 / 4 )) # The breaks can be spaced unevenlyīp + scale_y_continuous ( breaks = c ( 4, 4.25, 4.5, 5, 6, 8 )) # Suppress ticks and gridlinesīp + scale_y_continuous ( breaks = NULL ) # Hide tick marks and labels (on Y axis), but keep the gridlinesīp + theme ( axis.ticks = element_blank (), = element_blank ())īy default, the axes are linearly scaled. Figure 1 shows the output of the previous R code a basic scatterplot created by the ggplot2 package. ![]() # This will show tick marks on every 0.25 from 1 to 10
