Hello,
I've noticed the following problem with ContourPlot (I'm using
Mathematica 6..0.3) and a simple exponential function.
If you try the domain {x,-3,3}, {y,-3,3}
ContourPlot[Exp[-x^2 - 2 y^2], {x, -3,3}, {y, -3, 3},
Contours -> {.1,.2, .3, .4, .5, .6, .7, .8, .9, 1},
ContourLabels -> True, ContourShading -> False]
you only get one contour (the one corresponding to .1). However, if
you shrink the domain to {x,-2,2}, {y,-2,2}, surprisingly you get all
the contours (?)
ContourPlot[Exp[-x^2 - 2 y^2], {x, -2,2}, {y, -2, 2},
Contours -> {.1,.2, .3, .4, .5, .6, .7, .8, .9, 1},
ContourLabels -> True, ContourShading -> False]
Does anybody has an explanation for this? Thanks!
