Adjust Axis Scale in R: Complete Guide

In the R language, you can use the functions scale_x_continuous() and scale_y_continuous() to adjust the axis scales. Here are some common adjustment methods:

1. Adjust the axis range: You can use the limits parameter to set the range of the axis, for example, scale_x_continuous(limits = c(0, 10)) will set the x-axis range from 0 to 10.
2. You can adjust the interval between axis ticks by using the breaks parameter, for example scale_y_continuous(breaks = seq(0, 100, by = 10) can set the y-axis tick interval to every 10 units.
3. Set the coordinate axis tick labels: You can use the labels parameter to set the tick labels of the coordinate axis, for example, scale_x_continuous(labels = c(“A”, “B”, “C”, “D”)) can set the x-axis tick labels to “A”, “B”, “C”, “D”.
4. You can set axis titles using the “name” parameter, for example, scale_y_continuous(name = “Y-Axis”) sets the y-axis title as “Y-Axis”.

With these methods, the scale and labels of the axes can be adjusted as needed to make the charts clearer and easier to understand.
