Editing plot text

While our initial plot is a good start, there's a lot more we'll want to do to get it ready for "prime time." Let's start by making the x-axis readable, changing the axis labels, and making the y-axis ticks percentage.

The dataset usefulness_by_platform has been loaded for you.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

ggplot(usefulness_by_platform, aes(x = learning_platform, y = avg_usefulness)) + 
    geom_point() + 
    # Rotate x-axis text by 90 degrees
    theme(___ = element_text(angle = __, hjust = 1)) + 
    # Rename y and x axis labels
    labs(___ "Learning Platform", ___ "Percent finding at least somewhat useful") + 
    # Change y axis scale to percentage
    ___(labels = scales::scales::percent_format())
