[BUGZILLA #16846] how to remove filled.contour white interior grid?

[MichaelChirico]

looks like filled.contour function has been updated or something, and now it automatically adds a white grid inside the plot (inside filled contour plot area), but I don't know how to remove it.

i will give a little example:

x <- 1:12
y <- 1:12
xvals <- c(2,4,7,10,14,21,30,60,90,120,180,365)
fx <- as.numeric(as.factor(xvals))
filled.contour(fx, y, outer(x,y),
plot.axes= {
axis(2) ## plain
axis(1,at=fx,labels=xvals)
})

Plot before:

Plot Now:

As you can see the second plot (plot now), has a white grid in it, how do I get rid of that grid?

Thanks, Ricardo Faria.
