Also should be plotting against fitted() rather than regressors.

Both types of plots (vs. fitted values and vs. regressors) are very common. The former is a default plot in R, the first one that appears if you submit:

fit <- lm(y~X)
plot(fit)

The latter type of plot is called a "partial regression plot" or "added variable plot". They are discussed in any regression textbook, as well as wikipedia and probably dozens of other web sites.
