Your Turn

Use the expand argument within the scale_x_discrete() function to remove any gaps in your plot.

To read more about the expand() function, check out the ggplot documentation website. As you may have picked up in the video, I often end up just playing around with the values here in order to find something that gives me what I want.

There is also a great cheatsheet by Christian Burkhardt showing how expand() works.

  1. I forgot to put in the "add" to the last line, but it seems to have worked fine? What's the add for? scale_x_discrete(expand = expansion(c(.1, .35)))

  2. When I added a fig.width = 10 code in my Rmd setup code, only this plot in Rmd turned TINY. It returns to normal size when I remove the code, but then it's cut off when I knit. Without cutoff, I can only really read this graph when I knit it. I didn't see yours turn small when you set the width!?

I noticed when using both add and mult, I have change the nudge_x and nudge_y values within the geom_text. I see in this code, you are no longer using either and instead have gone to hjust. When is it "better" to nudge_x rather than hjust?
