[GRASS-dev] dropping d.linegraph, d.colorlist

Hi there.

any objections to removing the d.linegraph module from trunk?

it is off-topic, better implemented by pyPlot (which the wxGUI profile
tool is using), and yet another module to maintain.

also I would like to remove d.colorlist and replace it by a 'd.info -l'.

has anyone even used one of these modules?

thanks,
Hamish

No objections from my side.

Not during the last 17 years :slight_smile:

In other news I started to add a trend line to d.correlate in 6.5svn, and
am one y-value away from having it working. but I've run out of time and
blood sugar to work on it right now; so if anyone wants to take it on go
for it, otherwise it will have to wait until I have more time..

it also now displays R^2 value and prints the linear fit formula based
on the results of r.regression.line.

it would be good to (re)validate these things against R when all is done.
r.stats -A FP binning degrades the result a little, so it won't be exact.

i.spectral uses it (unless you use the -g option).

PyPlot can't be considered a *replacement* for any d.* modules until
there's a defined mechanism to use it such that:

1. GRASS_PNGFILE etc are honoured.

2. Any plot where the axes use spatial coordinates aligns with maps
generated by d.* commands.

#2 isn't applicable to d.linegraph, but #1 is.

If you're concerned about maintenance, I'd suggest rewriting
d.linegraph as a script which uses d.graph for output.
