Re: [Gnuplot-info] Waterfall / Cascade Plot

[howudodat <pe...@ho...>]

I wanted to bring everyone up to the most current code I am working with and
what's left for me to figure out.  I have only one remaining issue: My data
file does not have a first line as x axis tics.  Our raw data file will
/normally / look like:

1.3e8, -95, -110, -105....
1.4ee8, -97- -103, -102...
...

with there being 601 columns of Z data (time) by 8192 rows of frequencies. 
In order for the below script to work, I had to */insert /* a row of
,1,2,3,4 I'd like to not insert that row into our raw data if possible.

I am now plotting with: gnuplot -e"filename=SOURCE" plot.plg and it reads
SOURCE.csv and outputs to SOURCE.png and SOUCE-sub.png

#common parameters for both plots
set term png size 1900,1080
set datafile separator ","
set pm3d
set xrange[*:*] reverse
set key autotitle columnhead
set hidden3d
set view 45,75,,0.85
set palette defined (-120 "yellow", -70 "red", -30 "blue")
set xtics 0,50,600
set grid x y z

# plot all the data
set output filename.'.png'
splot filename.'.csv' nonuniform matrix using 1:2:3 with pm3d lc palette

# plot only what we are looking for +- a bit
set output filename.'-sub.png'
sedcmd="<(sed -n '1p;1000,3000p' " .filename. ".csv)"
splot sedcmd nonuniform matrix using 1:2:3 with pm3d lc palette

exit
