Sp + scale_y_continuous(labels = percent)įor dollar and scientific formats, type this: require(scales) # Remove y tick mark labels and grid lines For more examples, read the documentation of the function trans_new() in the scales R package. Possible values for labels are comma, percent, dollar and scientific. Scale_y_continuous(name="Stopping distance", limits=c(0, 150)) Sp + scale_x_continuous(name="Speed of cars", limits=c(0, 30)) + Sp <- ggplot(cars, aes(x = speed, y = dist)) + geom_point() P2 + theme( = element_text(angle = 45, hjust = 1)) P2 <- ggplot(iris, aes(Species, Sepal.Length)) + For example: # Create a new simple box plot To adjust the position of the axis text, you can specify the argument hjust and vjust, which values should be comprised between 0 and 1. P + theme( = element_text(face = "bold", color = "#993333",Ī = element_text(face = "bold", color = "blue", # face can be "plain", "italic", "bold" or "alic" For a vertical rotation of x axis labels use angle = 90. You can also specify the argument angle in the function element_text() to rotate the tick text.Ĭhange the style and the orientation angle of axis tick labels. The functions theme() and element_text() are used to set the font size, color and face of axis tick mark labels. For example to remove all axis ticks, use this: p + theme(axis.ticks = element_blank()). To remove a particular axis text or ticks, use element_blank() for the corresponding theme argument. Modify the appearance and the rotation angle of axis texts. element_text(color, size, face, family, angle, hjust, vjust).# Change axis ticks line: font color, size, linetype and lengthĪxis.ticks = element_line(), # Change ticks line fo all axesĪ = element_line(), # Change x axis ticks onlyĪ = element_line(), # Change y axis ticks onlyĪ = unit(3, "pt") # Change the length of tick marks # Change axis ticks text labels: font color, size and faceĪxis.text = element_text(), # Change tick labels for all axesĪ = element_text(), # Change x axis tick labels onlyĪ.top = element_text(), # x axis tick labels on top axisĪ = element_text(), # Change y axis tick labels onlyĪ.right = element_text(),# y axis tick labels on top axis Key ggplot2 theme options to modify the axis line, axis ticks and tick text labels:.The scale functions take the arguments breaks, labels and limits as inputs. Customize continuous x and y axes, respectively. scale_x_continuous() and scale_y_continuous().Customize discrete x and y axes, respectively. scale_x_discrete() and scale_y_discrete(). theme( = element_text(), = element_text()).The following function will be used to modify the axis theme and scale:
