How to have x- and y-axis fully labeled?

[echteinfachtv]

I would like to see all axis labelled with 1,2,3,4 without lacks.

See example graphic: http://i50.tinypic.com/ou1rtz.png

How do I have to change the code to achieve that?
Thanks!

Here is a video of a software called mathegrafix 9 which shows options to label the axes and change the ranges: http://www.youtube.com/watch?v=FztZiV2fdas You may want to take this as an example.

The software can also set arbitrary points, a feature also suggested here.
