Hallo,
I really like the new charts, but am struggling a bit to figure out how the labels for the PlotKit pie charts work. Seeing that there is not an xTicks: accessor for the pie chart layout, one would assume that the labels can be set in the dataset. But using a dataset like the one below cause's nothing to be displayed, while passing numeric labels seems to work fine.
dataset := PKDataset new name: 'data1'; addX: 'A' y: 1; addX: 'B' y: 2; addX: 'C' y: 3; addX: 'D' y: 4; yourself
Kind regards,
Mart-Mari

Hi
Alastair Tse took the time and rewrote CanvasGraph.js from scratch and called it PlotKit (http://www.liquidx.net/plotkit/). Now Seaise bindings are available at: http://squeaksource.com/seachart/ So whats new: - a new renderer that looks like Office 2007 - an experimental SVG backend - IE emulation, yes it works in IE!
There is also a demo application available at: http://seachart.seasidehosting.st/ that also displays some other seachart components. It uses a free template by Andreas Viklund (http://andreasviklund.com/)

You are right, #xTicks: would do the trick, but it's not there. The reason I didn't put it in the pie layout options is that the documentation says it's only available on line and bar layouts. http://media.liquidx.net/js/plotkit-doc/PlotKit.Layout.html As it turns out, the documentation is wrong and it works fine with a pie layout.
I published a new version (PlotKit-pmm.4) that adds #xTicks: to all layout options, and updated the included demo to set the labels. I also included a patch from the PlotKit mailinglist that allows to disable filling and stroking for line charts.
A dataset is really just a collection of points and a string. If you don't find the API a paragon of OOP then I agree. It's just a very close mapping of the existing PlotKit API. This makes life for me much easier.
If nothing is displayed this in general means that there was a JavaScript exception. Firefox and Extensions (Javascript Console, FireBug, Javascript Debugger) help in these cases.

Hi Philippe,
Thanks for PlotKit. It is looking really good. I do have a question about color schemes. I like the Office Color schemes, but I need something more tailored to my situation. So I want to use more primary colors (bright red, green, blue, and what not) for my pie chart.
I'm not sure how to do this. I see PKColorScheme, but am not sure how to pass it in to the Layout object or options object.
I've tried:
self layout officeColors at: 'colorScheme' put: PKColorScheme light.
and:
self layout options propertyAt: 'colorScheme' put: PKColorScheme light.
all to no avail. Any ideas on how I can use some of the ColorSchemes instead of the office colors?
Regards,
John

Hi
You are right, up until now there was no real support for custom colors because the documentation of PlotKit in this area is lacking. This is fixed with PlotKit-pmm.8.
You are now be able to do: aChart layout options colorSheme: PKPredefinedColorScheme light.
There is now also PKCustomColorScheme that allows you to specify manually the colors with Squeak Color instances. Color class >> #wheel: is a good starting point.
Cheers Philippe

Fantastic -- this works like a champ! Thanks much!
