(1) Use r.stats to output the z values. r.out.ascii is too hard
to manipulate using awk if the lines are long.
(2) r.stats -1qx will output z values with x,y coordinates:
1 1 10
1 2 11
1 3 15
.
.
.
100 1 43
100 2 44
.
.
.
This form appears to be what splot wants in parametric mode
(3) r.stats -1q will output just z values. You will need to write
a script to add blank lines between rows of data for
nonparametric splot. This two line shell script should do the
trick:
#!/bin/sh
cols=`g.region | awk '/cols/{print $2}'`
r.stats -1q $1 | awk 'NR%cols==0{print ""};{print}' cols=$cols
Note, this depends on your version of awk accepting the
cols=number on the command line. Not all versions of awk will
accept it.
(4) Note - I haven't tried gnuplot with splot yet. I just wanted
to disseminate these ideas so other could try.
