Click here to see the example. --------------------------------------------------------------- This is a SAS/Graph version of http://rosettacode.org/wiki/Mandelbrot_set#Fortran I used simple data steps, and a SAS/Graph Gplot of the points. In this version I add colors for each 'level' - at first I used symbol statements for each color, and let gplot assign them (via "plot y*x=colorvar") but that was a little slow and inefficient, so I got a little tricky and suppressed the gplot markers, and annotated each dot - this sped things up by about 50% (which is important, because I also set it up to allow drilldowns, and therefore the interactive response time was important). ----- I set up macro variables at the top of the program where you can easily control which piece of the Mandelbrot set to show (this let's you "zoom in" on a section). I also annotated a 3x3 grid (invisible/behind the chart) with html href drilldown, and the URL generates the Mangelbrot graph of that section of the grid ... the caveat being that you must be on the SAS internal network for that to work! If you've got your own SAS/Intrnet server, I'll be happy to send you a copy of the SAS/Intrnet job, so you can run this on your machine :) Back to Samples Index
