comment Rasterizing a plot make axes ticks invisible
@Jens: I used your suggestion, too, to solve a similar problem. I used FrameStyle->Thickness[0.003], FrameTicksStyle->Thickness[0.003] in my framed plot to get both the frame and the ticks in the right width.

comment Several functions in one RegionPlot with different grayscale
@cormullion Problems like this occur when you are in the middle of a Bachelor thesis in Theoretical chemistry and you don't really know what you are doing - sigma is an expression for nonlinear conductivity in an easy 1D model, and the number of roots in dependance of some coefficients is interesting. Well, kind of. But I made some mistakes in the formula given here, and for the actual thesis I switched to 2D graphics. These examples helped me a lot with GrayLevel though, I did not know the command before.

Thank you very much, your answer definitely helped me understanding the use of the Graphics and Inset options.

comment Using graphics primitives to draw a cross as inset in graphics
Just out of interest: why does the cross stay symmetrically if I combine it with a plot with differently scaled axes? Doesn't the a refer to the values of the x and y values where the lines of the cross end?

comment Using graphics primitives to draw a cross as inset in graphics
Using inset also makes it possible to locate the cross anywhere: a = 0.2; t = 6; Graphics[{Circle[], Inset[Graphics[{AbsoluteThickness[t], Line[{{-a, -a}, {a, a}}]}], {1, 0}, Center, 2 a], Inset[Graphics[{AbsoluteThickness[t], Line[{{-a, a}, {a, -a}}]}], {1, 0}, Center, 2 a]}, Frame -> True, ImageSize -> 250] shifts the cross to the right.

comment Problem with high parameter values in ParametricPlot
Thanks a lot, @Mr.Wizard, that helps! But still the curve does not look the way I expected it. With another program (Zplot) I get completely different results. Is it possible that I have some numerical issues here with the cotangens hyperbolicus or something?

comment Problem with high parameter values in ParametricPlot
Oh, I thought I needed that because Im does not work for symbolic expressions. But the plotting evaluates it... I will delete that. Does not solve the problem though.

comment AxesLabel in RegionPlot does not work
That explains it - FrameLabel works for Frame, AxesLabel for Axes, and the two are completely different things. Thanks for your answer!
