Dear Abu, 1. I had commented out in desperate hacking attempt to get something in browser!
2. There is no /misc/canvas.l file. 3. I did try in side the script (main go) But it didn't work. 4. Did pil zappel.l -main -go + Then it showed red line and changing random numbers. But no running plot. 5. Had to fiddle, then figured out by clicking single tab followed by step, I could get moving plot. 6. Not very smooth, but great for moment! Regards. Alabhya
