Hi Offray,
You can add ticks as follows:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
c := (1 to: 100) collect: [ :i | 50 atRandom @ 50 atRandom ].
g := RTGrapher new.
d := RTData new.
d points: c.
d x: #x.
d y: #y.
g add: d.
g axisX noTick.
g axisY noTick.
g addDecorator: (RTVerticalValuesDecorator new addAll: #(10 25)).
g addDecorator: (RTHorizontalValuesDecorator new addAll: #(10 25)).
g
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
For the legend, there is actually no such a support. However, it should be easy to add a new rule, as a subclass of RTLegendItem
Cheers,
Alexandre

So, for example, I would like to say that instead of having the default 1xn column of color labels, as now, I want them organized over a nxm matrix, so they suit better different graphical objects and layouts.
