I have a scatter plot, but the axis labels are overlapping, and the range is too wide. How do I manually set the axis limits and rotate the labels so they are readable?
Axis limits in R are set using the xlim and ylim parameters in base plot or coord_cartesian in ggplot2, while label orientation is adjusted via the axis.text argument within the theme function.

You should implement these specific adjustments to resolve your axis rendering issues.
- Define the coordinate boundaries using coord_cartesian to zoom without discarding data points
- Apply theme elements to modify text orientation for axis labels
- Set the angle argument within element_text to ensure complete readability
You need to use the xlim and ylim arguments in the plot function, or the scale_x_continuous function if you are using ggplot2. Rotating labels is best handled through the theme function by setting the axis.text.x angle to 45 degrees. Stop overcomplicating your visualization logic; these parameters are built specifically to solve exactly this kind of layout clutter.
I remember back when I was standardizing our reporting suite, I fought with overlapping labels for an entire afternoon before realizing I was trying to force too much data into a tiny viewport. I finally settled on just shifting the rotation and tightening the scale, which cleaned up the dashboard enough that my stakeholders finally stopped complaining about legibility.
It is really just a matter of getting your theme settings correct in ggplot2. Once you stop treating the plot as a dumping ground for every single data point and start narrowing your focus, the visual noise disappears naturally.
Using base R plotting functions is fine for quick checks, but it becomes a massive headache when you actually need to manage complex visuals. You are probably better off switching to ggplot2 because it handles scale limits with scale_x_continuous and rotation via theme elements much more gracefully than the standard plot functions ever could.
Base R is great for speed, but once you hit layout constraints like overlapping text, the ggplot2 library is simply the superior tool for enterprise-grade data visualization.
Just use ggplot2 and be done with it. Trying to force base R to render clean, readable axes is a waste of engineering time when there are declarative packages designed to automate label stacking and limit scaling. If your labels are overlapping, you have too much noise, and you should probably reconsider whether that visualization even provides meaningful value to the end user. Clean your data representation or hide the redundant labels entirely.
