RE: st: Changing the scale of a graph

[Nick Cox <n.j.cox@durham.ac.uk>]

In my view graphs are generally better at showing outliers than any numerical procedure. 

I don't know what you mean by "integrated command" here. If you want a command to make the decisions you would make about outliers, you would need to program that. For what I do, automatic decisions about outliers don't work well and are a bad idea. People with massive datasets arriving all the time might need to do things differently.

Nick, would you suggest to check for outliers before drawing the graph then, or is there any integrated command?
