Ok - I've got a question: I'm just trying to get a decent plot out of Mathematica for a function that returns some very small values. However, I won't worry you all with the function as the problem occurs in the Plot: The command: Plot[x*10^-29, {x, 0, 100}, PlotRange -> {0, 10^-27}] Gives me a little graph of nothing - the PlotRange is apparently ignored, and is treated as if I had typed {-0.5, 0.5} for the PlotRange; (I get this information from FullOptions). Now, one solution would be to scale the function up a bit and use Ticks to simulate being way down under, but I'd rather not do that - I just want to Plot where I want to Plot. I tried some odd replacement rules to get a FullForm that looked like it had the proper PlotRange, but when I did a Show of that Graphics object and then another FullForm, it appeared that PlotRange had secretly returned to {-0.5, 0.5}. Is there a hidden limit on PlotRange? Can it be changed? martind at carleton.edu
