Hi,
I was working through the pie-chart tutorial in the main repository at
self<https://github.com/russellallen/self/tree/5e8031667b5d549d4b4a6cec41e06aa97c3c9c45>
/ docs<https://github.com/russellallen/self/tree/5e8031667b5d549d4b4a6cec41e06aa97c3c9c45/docs>

/ PieChart<https://github.com/russellallen/self/tree/5e8031667b5d549d4b4a6cec41e06aa97c3c9c45/docs/tutorial/Morphic/PieChart>
/ *Changes.html*
I think I did everything right but I am getting an error
'Lookup error, 'mapBy:' not found'
I believe this is a valid selector, but I am only just starting with the
language
this is the 'copyNewData: data'' slot' text
> | new. wList |
> new: copyRemoveAllMorphs.
> wList:
> data copy mapBy: [| :val. w |
> w: pieWedgeMorph copyRemoveAllMorphs.
> w color: paint copyRandom.
> w amount: val.
> ].
> new addAllMorphs: wList.
> new
I checked the handbook, mapBy: is a valid selector
http://handbook.selflanguage.org/4.5/usefulselectors.html
Any ideas where I have gone wrong?
Kind regards,
Stephen
