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 > On May 6, 2018, at 9:13 AM, Offray Vladimir Luna Cárdenas > <offray.l...@mutabit.com> wrote: > > Hi, > > Here is the improved version: > > <iiboahmkfajnlmam.png> > > As you can see, now I coded colored years functionality (I thought that > colored histograms, following a criteria, would be supported by default, but > I was unable to find any documentation or example about it).
