average profile on a box

[mmetois]

Hi,
Could it be possible to think about a new feature for the plugin that would allow to plot averaged profiles ?
i.e. we often plot the averaged value of a raster along a profile line with a specified width (eg 2km around the main profile line)
Alternatively, without calculating the average, could it be possible to plot a set of parallel profiles in a polygon ?
thanks,
Marianne
