Graphics, Figures & Tables ⇒ pstricks | Positioning of Pictures

[argan]

Hi,

I have a lot of problems trying to position my pictures with pstricks. I wish to place two graphs next to each other, and by googling I found out I could do that using minipage. But still, I don't really understand what is happening with them. They seem to somehow start at zero, but then they extend up beyond the page for some reason. And if I change the axes setting, the only thing that happens is that they are cut off instead.

My code for the two figures:

These are two images of when I'm using the axes set to (0.02,0)(1,5) and (0.02,20)(1,25) respectively.

I guess I have a general question as well; when you write the begin{pspicture} and the coordinates after that are supposed to be entered, what are the coordinates relative to? Also, sometimes I have seen that only one set of coordinates is entered, what does this mean? I tried too look for this in the documentation, but I didn't really find anything useful. I used (4,4) in the code above just because it happened to work.

Thanks,
