Thomas,
This would be one way:
Show[Graphics[Line[{{3, -5}, {3, 5}}]],
PlotRange -> {{-0.001, 6}, {-5.001, 5}}, Axes -> True];
Or you could add the line to another plot this way:
Plot[x^2/6, {x, 0, 6}, Epilog -> {Line[{{3, 0}, {3, 6}}]}];
Or you could use the package ImplicitPlot:
ImplicitPlot[x == 3, {x, 1, 4}, {y, -5, 5},
PlotRange -> {{-0.001, 6}, {-5.001, 5}, Automatic}];
ImplicitPlot seems to be a little tricky. You have to use the form where both the x
and y range is given, and then if you want to get a nice PlotRange you have to use
three arguments in PlotRange because this is really a contour plot which requires the
third argument.
