Hi Mark,

In case you are not tied to PlotMorph, you can use Roassal for your drawing. Roassal supports Grapher, which is a resurrection of GraphET. 

Documentation is available on:
http://agilevisualization.com/AgileVisualization/Grapher/0203-Grapher.html

Open Pharo 6, load Roassal using:
Gofer it
    smalltalkhubUser: 'ObjectProfile' project: 'Roassal2';
    configurationOf: 'Roassal2';
    loadDevelopment


And type in a playground:
b := RTGrapher new. ds := RTData new. ds noDot. ds points: (0 to: 3.1415 * 5 by: 0.01). ds y: #sin. ds x: #yourself. ds connectColor: (Color red alpha: 0.4). b add: ds. ds := RTData new. ds noDot. ds points: (0 to: 3.1415 * 5 by: 0.01). ds y: #cos. ds x: #yourself. ds connectColor: (Color blue alpha: 0.4). b add: ds. b

You will get:

Cheers,
Alexandre

OK I am now more confused as I see that suggestion does not work.

Looking for graphing packages I tried to load GraphET - which gives a
popup box

GraphET has not been marked as tested for Pharo6! Do you want to
continue (installation could fail)

Which seems to me to be a good feature,

But does imply some packages have been added and marked as tested
without being tested which does raise a large doubt in my mind as to
what is supposed to work and how can I trust parts of the system which
are marked as working.

Thanks for the report since I need PlotMorph too for a project.
What you see is the consequence of lack of validation of published
packages. This is years that I'm saying that I need someone to work on
that.
We got money from inria for Pavel to work on it but the bootstrap was
more important :).
