Drawing grid and other graphs on top of FreqScope or FreqScopeView

[Pawle]

Hello list
Is it possible to put a FreqScopeView or FreqScope on a UserView and then
draw on it with Pen. I would like to have the spectre being drawn in
realtime an then have some lines drawn on top of it. I know how to use
FreqScope and Pen, but I dont know how to put them together.

DrawGrid will do that for you. See the help file.

this will draw on a UserView. put it on top of the FreqScopeView (same
bounds)

and set the background color to transparent and you should see the scope
behind the lines


(
w = Window.new.front;
u = UserView(w,Rect(20,20,300,300));
// the Spec can define its preferred grid system
x = \freq.asSpec.grid;
y = \amp.asSpec.grid;
d = DrawGrid(Rect(0,0,500,300), x,y);

u.drawFunc = {
d.draw
};
)

Oh so simple, I've made the mistake of putting the freqscope in the
userView. Thank you.

its a useful trick to stack views on top of each other.

the only issue is that the top most one will get the clicks.
