It took me 107 previous days of plotting to come up with an elegant idea: searching the best plot among many different variants can easily be done by working instead on a video of that plot! Then you can chose a frame to plot, it is both practical as well as you get a nice animation for free!
Some code snippet for video generation.
# generate all .svg in results, then:
cd results
mkdir pngs
for f in *.svg; do convert $f pngs/${f%.*}.png; done
ffmpeg -r 24 -i pngs/%d.png -pix_fmt yuv420p -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" out.mp4
