[Newbies] A morph for doing 2D plots

[Herbert König]

aahh, now I saw the code in the class comment.

I copied it into a workspace like this:

|mgRelation|
mgRelation := MGRelationOnLeftToRightBlock new.
     mgRelation block: [:x|x squared].
     mgPlotMorph addRelation: mgRelation.

and it raises a debugger.

First it should be possible to run it from the browser. My example 
methods usually have "self example1" in the method comment.
Secondly the example should work after just loading the code :-))

At least now I understand that you had a function plotter in mind. Now 
MGRelation starts to make some sense.

Ok, reading the whole comment I did:

|mgRelation mgPlotMorph|
mgPlotMorph := MGPlotMorph new.
     mgPlotMorph openInWorld.
mgRelation := MGRelationOnLeftToRightBlock new.
     mgRelation block: [:x|x squared].
     mgPlotMorph addRelation: mgRelation.

See how stupid your users are :-))



Cheers

Herbert
