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.

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. Feb 5 accepted Problem with high parameter values in ParametricPlot Feb 5 comment Using graphics primitives to draw a cross as inset in graphics Thank you very much, your answer definitely helped me understanding the use of the Graphics and Inset options. Feb 5 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? Feb 5 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. Feb 5 asked Using graphics primitives to draw a cross as inset in graphics Jan 22 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? Jan 21 revised Problem with high parameter values in ParametricPlot deleted 88 characters in body Jan 21 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. Jan 21 asked Problem with high parameter values in ParametricPlot
