is there a function which plots the phenology of a time series?
d.profile is doing it spatially but I would like to look at the temporal curve
of various raster which are a time series.
e.g. d.profile input=raster.jan, raster.feb, .... raster.dec and then select a
pixel/area in the image and receive a time profile for each pixel which I
selected.
thanks in advance, Martin

hi Martin,
you may use
i.spectral help
Description:
displays spectral response at user specified locations in images
Modifying this script a bit it you could use g.mlist to insert
your time series and visualize. Needs gnuplot.
However I looked at the script but cannot figure out how/where to insert
g.mlist.
I assume I have to substitute RASTERMAPS="$GIS_OPT_band1 ... " somehow with
the g.mlist output, right?

replace the two RASTERMAPS lines with:
RASTERMAPS="`g.mlist sep=, pattern='*'`"
Backwards `quotes` fills that part of the string with the output from
the program within them, run the inner g.mlist part first to see what
will happen.
Double "quotes" around the string are just precautionary.
If you are using less than 8 maps, just use i.spectral without
modification.
