The plot a month later

Over the past month I have worked solid on rewriting the plot facilities


Figure 1, low resolution web image, comparable as shown at the beginning of May except a different geographic projection, done using wildly different software.

This is a quick look at what is new, the full thing is about to be used as part of a major article at the Talkshop.

Why? I was thoroughly fed up with fighting gnuplot, drives many people half crazy trying to get it to do what is wanted, all too often it simply can’t. In this case the final straw was no way of disabling automatic smearing of colour, nor can it draw literal filled polygons. (very amusingly given the authors say it can’t it then when writing out SVG format proceeds to write out filled polygons… can’t make it up stuff)

I was already using GLE, a tool with ancient origins. This will do what I say so all those polygons are drawn one at a time. The whole thing is very complicated, more so since my code writes GLE code and data before passing the whole lot over for plotting (GLE in turn calls ghostscript with postscript code, wheels within wheels)

There is more…
