It might help seeing your graphs here, too.

I'm surprised that's showing up here for the first time, I don't recall that showing up before, but as we've noted at #34233 there were changes a while back in mpl that our code failed to keep up with. One thing one could try, then, is to add, in addition to the rcParams['axes.formatter.use_mathtext'] = True at #34233 is to see whether one of these (or whatever the right syntax is) might help: rcParams['axes.formatter.use_offSet'] = False rcParams["axes.formatter.offset_threshold"] On Thu, Mar 14, 2024 at 10:04 AM David Joyner <wdjo...@gmail.com> wrote: Hi: I'm trying to show my students a plot of a rational function whose graph is basically 1, so I plotted f(x) = (x^2+0.0001)/(x^2+0.0001000001) However, there is a problem: Note the difference between plot((x^2+0.0001)/(x^2+0.0001000001), (x,-10,10)) (which dips down near x=0) and plot((x^2+0.0001)/(x^2+0.0001000001), (x,-10,10), ymin = -0.1, ymax = 1.5) (which basically looks like a straight line).

Can anyone tell what is going on here? I'm happy to attached jpgs of the plots I get, if desired. For comparison, it appears that Sympy plots this correctly. - David Joyner -- You received this message because you are subscribed to the Google Groups "sage-support" group.
