(2) I'm asking about the 2D Plot, but not simply restricting the plotting range. The plot is obviously not single-valued, but there are portions of the double-value that take the lines to infinity (For example, coming from infinity on q = p + const in the positive direction, and going to infinity on q = p - const in the negative direction). If it were a parametric plot, I could restrict the range of the parameter, but that's not really relevant here. | |

@Necarion (1) In fact, this is what I normally do: ContourPlot[Evaluate@Thread[Numerator@Together[fulltable /. Equal -> Subtract] == 0], {p, -10, 10}, {q, -10, 10}, PlotPoints -> plotpoints]. Somehow I focused on the exclusions. (2) Do you mean something like this?: ContourPlot[.., {p, -2, 2}, {q, -2, 2}] Or are you asking about the 3D plot?

| Jun 1, 2015 at 22:44 | comment | added | Necarion | Thanks. That seems to have resolved the bulk of my difficulties, even if I'm not totally sure why it did so. I do have 2 related questions, though. First, and I know I'm being picky here (i.e., this isn't terribly important), can I smooth the graphs out again so those 'gaps' are filled up in a sensible manner. Second, is there an easy way to exclude the portion of the graph that goes between zero and infinity (the portions that bend over backwards). They aren't meaningful and only confuse everything. Thanks! | |
