I was thinking something like this.

I agree that would be great. Incidentally, have you considered using canvases to draw your envelope?
nope. I ca't imagine how... looking at the [cnv] help doesn't suggest me anything.
however, this is what I did: http://xaero.ath.cx/cms/en/adsr-new.html it can be useful for graphing an ADSR, not for editing it.
I appreciate recently added datastructs new features.
however I think they still miss a big functionality: often, to graphically represent a structure of data, are needed various type of calculations; it is pretty unuseful i.e. draw a polygon with all coordinates referred to 0,0 (object's center).
in order to paint a simple adsr struct, in addition to the template, I have to create a "data-controller", which prepares *ALL* points of the adsr-graph (e.g.: x1,y1,x2,y2,....), *NOT* only the a,d,s,r.
i guess this feature has been requested many times, but, wouldn't be better have the ability of making additions,subtractions,etc directly inside the drawpolygon declaration?
in that case, plotting that adsr line it's just: [drawpolygon 0 900 0 0 a 100 (a+d) s (a+d+100) s (a+d+100+r) 0]
what pd developers says about this?
