Just FYI, #6035 partially resolves this.

However, 

sage: plot(tan,-20,20, detect_poles='show')
sage: plot(tan,-20,20, detect_poles=True)

shows that 'show' still keeps the "missing" points (which include not just the asymptote but also the high slopes on either side) and that True doesn't create a uniform height as one might desire in the Description.

Description changed to indicate this successful partial resolution, however!

  • Ticket #3985 – Description

    initial v3  
    1 Plotting functions like 1/x, tan, etc. have asymptotes essentially plotted in Sage at this point.  This is okay, except that the scale is way out of whack, so things look very odd.  Sage should either remove the asymptote piece of these plots somehow (how is not obvious) or fix the ymin and ymax in show so that it just looks like the asymptotes are plotted. 
    2 E.g.
     1Still need improvement on plotting of asymptote of e.g. tan or 1/x, especially when detect_poles != True.  Ideally one has an output similar to
    32{{{
    43sage: plot(tan,-20,20).show(ymin=-5, ymax=5)
    54}}}
    6 except automatic detection of the ymin and ymax.
     5but just straight out of plot.
