I've been playing with this, and I haven't been able to come up with a working translation of that code fragment.
Here's my current best guess, though it still does not work: load 'graph' gdopen'' NB. Create drawing surface gdcolor 255 0 0 NB. set the color gdpen 2, PS_DASH NB. pen width 2, dashed line gdlines 0 1000 1000 0 NB. draw using current pen gdshow'' I suspect that the graph addon needs some work. -- Raul On Thu, Apr 6, 2023 at 11:57 AM Michal Wallace <[email protected]> wrote: > > https://code.jsoftware.com/wiki/Help/JforC/Graphics > > ... says you can do this to make an isigraph pop up: > > load 'graph' > gopen '' > > > but... > a) the verb seems to have been renamed to `gdopen` since this was written > and > b) no window pops up when you call `gdopen` > > (tested in jQt for windows, j902 and j9.4...) > > Do we need to fix the code, or the docs? > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
