Reactive mode

[gsabbih6]

auto f = gcf(false);
auto ax = f->gca();
auto p = ax->plot(ax, x, y); // draws once
p->color("red").line_width(2); // draws twice more
wait();

I am trying to use reactive mode for and interactive realtime graph but there is no gcf class that takes a false parameter in line 1 above. Any help?

This code was copied from the documentation directly

The interface needed to change and I forgot to update the docs. You can try:

figure_handle f = figure(true);

or

figure_handle f = figure(false);

Like in the geoplot_7.cpp example.

You show also replace wait() with:

show();

or

draw();

If you need to update your figure very often, it'd be better to use the non-reactive mode and call draw() explicitly, like in the geoplot_7.cpp example.

I'll update the docs to fix that.
