Firtst you can test by typing
jpath '~Demos'
if it returns a path name like ..../addons/demos then most likely, it has
already set and you need not worry.
If that returns the same ~Demos , then if you use jconsole under window or
linux, type inside jconsole ( not jhs broweser),
xedit '~config/folders.cfg'
notepad or other editor will open a file, add the following line,
Demo ~addons/demos
save and restart J, and test the <jpath '~Demos'> again.
Assuming ~Demos is ok, in jconsole type (need internet connection)
laod 'pacman'
'update' jpkg ''
'install' jpkg 'ide/jhs graphics/plot graphics/afm demos/plot general/misc
math/misc'
shutdown jconsole. start JHS,
after connecting jijx, in the browser, type the following,
require 'plot numeric trig'
plot 10?10
load '~Demos/plot/plotdemos.ijs'
plotdemos 0
plotdef 'show';200 100
plotdemos 1
