# To subscribers of the xforms list from "Reed Riddle" <drriddle@qwest.net> :
Hi all,
I don't remember if I ever posted this...I think I did, but it was a
while ago, and I have been using an old library build since then. The
new one doesn't have it, so I thought I might as well toss it out
there. This is to allow the replacement of a point value in an xyplot
overlay; it's standard for the xyplot base plot, but I needed one for
the overlay as well.
void
fl_replace_xyplot_overlay_point(FL_OBJECT * ob, int i, int ID,
double x, double y)
{
SPEC *sp = ob->spec;
if (i < 0 || i >= sp->n[ID])
return;
if ((sp->x[ID][i] != x) || (sp->y[ID][i] != y))
{
sp->x[ID][i] = x;
sp->y[ID][i] = y;
fl_redraw_object(ob);
}
}
I didn't have any issues otherwise today while I was working with the
library, but I'm working on a small project right now. I'll try to get
more "exercise" in tomorrow. :)
