Use scale_x_discrete to Display Subset of Items on x Axis in RĪnother useful feature of the scale_x_discrete function is to eliminate some items from the x-axis and draw only a handful of them. library(ggplot2) library(gridExtra) p1 <- ggplot(Loblolly, aes(x = Seed, y = height)) + geom_boxplot(fill = "cyan") p2 <- ggplot(Loblolly, aes(x = Seed, y = height)) + geom_boxplot(fill = "orange") + scale_x_discrete(limits = rev(levels(Loblolly$Seed))) grid.arrange(p1, p2, ncol = 2, nrow =2) Notice that the data-set name comes first, followed by the $ symbol, and then we specify the x-axis data that needs to be reversed. It’s often the case that the order of items on the axis needs to be reversed, and the easiest method to accomplish this is to set the limits parameter of the scale_x_discrete parameter with the value of rev(levels(dataset_name$X_axis_items)).

In this article, we construct multiple boxplot graphs using ggplot and geom_boxplot functions to demonstrate the effect of different parameters in scale_x_discrete. Scale_x_discrete is used to set values for discrete x-axis scale aesthetics. Use scale_x_discrete to Reverse Order of Items on x Axis in R Plot axis = dup_ axis ()) + scale_y_continuous (sec.This article will introduce the scale_x_discrete function in R. ggplot (data = mpg, aes (x = displ, y = hwy)) + geom_point + scale_x_continuous (sec. dup_ axis is a shorthand for creating a secondary axis that is a duplication of the primary axis, effectively mirroring the primary axis. # Box plot : change y axis range bp + ylim(0,50) # scatter plots : change x and y limits sp + xlim(5, 40)+ylim …įrom ggplot2 2.2.0 you may use the sec.

To change the range of a continuous axis, the functions xlim() and ylim() can be used as follow : # x axis limits sp + xlim(min, max) # y axis limits sp + ylim(min, max) min and max are the minimum and the maximum values of each axis. For example, the following two plot specifications are. It is also possible to map discrete variables to position scales, with the default scales being scale_x_discrete() and scale_y_discrete() in this case. As you can see based on the previous R syntax, we specified the axis limits within the scale_x_continuous command to be within the range of -10 and 10. Key ggplot2 R functions: Discrete axes: scale_ x _discrete(name, breaks, labels, limits): for x axis scale_y_discrete(name, breaks, labels, limits): for y axis Continuous axes:, Figure 2: ggplot2 Density Plot with Broader x- Axis due to scale_x_continuous Function. In each of these two cases, the functions to be used for setting axis ticks are different. x or y axis can be discrete (grouping variable) or continuous (numeric variable).

It is possible to use these functions to change the following x or y axis parameters : axis titles axis limits (data range to display), Source: R/axis-secondary.R This function is used in conjunction with a position scale to create a secondary axis, positioned opposite of the primary axis. The functions scale_ x _discrete() and scale_y_discrete() are used to customize discrete x and y axis, respectively. axis would be nice for discrete scales as well, such as when you have various ways to refer to factor levels (short and long) and the like. axis argument of their scale_continuous() brethren. So editing the type variable to a numeric variable and then changing the label would work:, scale_y_discrete() and scale_ x _discrete() currently appear not to support the sec. The scale_x_discrete function does not have a second axes argument, but scale_x_continuous does. For simple manipulation of scale labels and limits, you may wish to. Scale_x_discrete() and scale_y_discrete() are used to set the values for discrete x and y scale aesthetics.
