This should use "Object categoryForUniclasses", not hard-code the category name. Also, did you test this works after loading the project? Meaning my analysis of #declareAndPossiblyRename: was wrong? - Bert -

New Graphing tools
by Ricardo Moran 25 May '11

25 May '11

Hi guys, following Bert's request I've resumed some of my work for GSoC hoping that it could be included in the next Etoys release :) This is a new version (a complete rewrite, actually) of the graphing tools. This time I've followed Steve's idea of a simple number line object and the ability to change the scale of the playfield so that kids could make their own graphs (you can find the original conversation in this old thread<http://answerpot.com/showthread.php?899620-Copying+Graphing+tools+and+Speec…> ). You can see in the attached project that the playfield includes two new objects (horizontal number line and vertical number line). This objects have an extra category called "number line" with a few properties such as: * increment * min/max value * scale You can change the scale to define how much pixels will mean a unit of the number line. The increment will define the distance between labels. You will also find a new category on Playfield named "coordinate system". This category has: * origin at center? * origin * scale x * scale y Using this properties you can define a different coordinate system for the objects you throw inside the playfield. In the attached example I defined a playfield with the origin at 50@50 (this means 50 pixels from the bottom and left sides), an x scale of 1, and an y scale of 30. You can see how the position of the star changes acording to this scale while you move it inside the playfield and how it returns to its original scale when you pick it up and drop it outside the playfield. For now it's just a proof of concept. A lot of things still don't use this new scaling (i.e. #forward:). But I want to know what you think about this direction. Also, how much time do we have until the deadline? I have two exams tomorrow so I'm probably off for today. We can discuss this stuff at SqueakFest :) See some of you in Montevideo! Cheers, Richo
