R help - Feb 2011 - waveThresh plot axis

Dear,

I am using WaveTresh for Haar Wavelets. It works all fine exept when I
want to adjust the axis on the wavelet coefficient plot:

input:    wlh_ponds<-wd(input_waves[,1],
family="DaubExPhase",filter.number=1)
plot:      plot(wlh_ponds,scaling="by.level")

My problem is twofold-I want the original x-axis of the data on that plot, not
1/2 of the
axis. This would make my plot more clear for comparison with the
original data series.

-I want to cut of a part of the graph because I added columns with 0's
to make my series 2^n. Now I want to cut them of again.

It may look like a simple problem, but things like "xlim" don't
work
with this kind of plot.

Thank you,
Best wishes
Eva Ampe

I just ran into this with dates and I finally had to just use "which"
on the
input data with an expression for the xlim values, d[which(
d>xi)&(d<xf)) ]
for example. The plot documentation seems to refer to use of raw data range
instead of xlim for figuring label params. Is there an implemented option
to change this?
