[comp.sys.next] WingZ graphics

agm@cs.brown.edu (Axel Merk) (12/16/90)

For those who looked at WingZ and wondered why it takes more than half
an hour to create a reasonable looking graph with about 5000 data
points, check out how WingZ connects two data points in a line graph:
	newpath
	126.050003 191.5 moveto
	126.150002 191.199997 lineto
	stroke
	126.150002 191.199997 moveto
	126.150002 191.199997 moveto

	newpath
	126.150002 191.199997 moveto
	126.199997 191 lineto
	stroke
	126.199997 191 moveto
	126.199997 191 moveto

Even for someone who does not know PostScript, it should be fairly
clear that there Informix felt like burning MIPS - for someone who
knows the source code, it would probably take less than a few hours to
fix this and thereby speeding up the graphics output by a factor of at
least 3.
