Hello,
When I give the command
ContourPlot[(1-Exp[-1/((x)^2+(y)^2)/10]),{x,-1.0,1.0},{y,-1.0,1.0},
PlotPoints ->{50,50},
Contours -> {.1,.2,.3,.4,.5,.6,.7,.8,.9,.99, .99999999},
ContourShading ->False]
I get what would be to expect, i.e. all the contours. But if I change
slightly the domain,
say "{x,-1.1,1.1},{y,-1.1,1.1}", the majority of the contours
disappear. And they do not appear even if I increase PlotPoints to 200
or more.
Does anybody know the reason of this strange behaviour? And how to avoid
it?
Thanks in advance,
Pedro Santos
