Question

I’m using ggplot2 and attempting to create an empty plot with some basic dimensions, like I might do w/ the stock plot function like so:

plot(x = c(0, 10), y=c(-7, 7))

Then I’d plot the points with geom_point() (or, stock point() function)

How can I set that basic plot up using ggplot? I’m only able to draw a plot using like:

ggplot() + layer(data=data, mapping = aes(x=side, y=height), geom = "point")

But this has max x/y values based on the data.

Answer 1

There are two ways to approach this:

Basically the same approach as with base graphics; the first layer put down has the limits you want, using geom_blank()

ggplot() +
  geom_blank(data=data.frame(x=c(0,10),y=c(-7,7)), mapping=aes(x=x,y=y))

Using expand_limits()

ggplot() +
  expand_limits(x=c(0,10), y=c(-7,7))

In both cases, if your data extends beyond this, the axes will be further expanded.
