Full_Name: Marco Gruteser Version: 1.7.1 OS: Win XP Submission from: (NULL) (129.34.20.16) Let's generate a dummy filled.contour plot
x <- 1:10 y <- 1:10 z <- array(rep(0, times=100),dim=c(10,10)) filled.contour(x,y,z)
And try to add some points to it, e.g.
points(8,2) points(6,2)
The points show up misaligned with the axis somewhere at 9.9,2 and 7.5,2 It appears that the "z value legend" on the right may have distorted the axis.
