[Scilab-users] Callback in checkbox for multiple figures

[Stéphane Mottelet]

Hello Iza,

If your uicontrol and your Axes are children of the same Figure, you can 
recover the Axes relatively, like in this small example:

function  cbfun()
     h=gcbo();
     ax=h.parent.children(2);
     ax.children(1).visible=h.value;
endfunction  

scf(0)
clf
uicontrol("style","checkbox","backgroundcolor",..
[1  1  1],"value",1,"callback","cbfun");
t=linspace(0,2*%pi,100);
plot(t,sin(t))
plot(t,cos(t))

scf(1)
clf
uicontrol("style","checkbox","backgroundcolor",..
[1  1  1],"value",1,"callback","cbfun");
t=linspace(0,2*%pi,100);
plot(t,sin(t))
plot(t,cos(t))
