Improves the setting of xlims in the scatter plot

* Fixes a bug in which the right-most data point is not includes by
  using the `drange` include_stop argument
* Removes unneccersery code that is repeating the operation of plotting
  a border
* Add a space between the final data point and the right-hand border
