Hi Hernán, Sorry for the late reply. Regarding your first question, you can do: -=-=-=-=-=-= g := RTGrapher new. d := RTData new. d connectColor: Color blue. d noDot. d points: (-3.14 to: 3.14 by: 0.1). d y: #sin. d x: #yourself. g add: d. g axisX numberOfTicks: 10; numberOfLabels: 5. g -=-=-=-=-=-= As you can see, the line "g axisX numberOfTicks: 10; numberOfLabels: 5.” allows you to set the number of ticks and the number of labels. Regarding your second question, where can I find the file OrderedCollection_3712516797.obj ? Or, how can I reproduce it. Anyway, I believe the problem is that you have too many points. In this case, I suggest you to reduce the number of points. For example, a slight variation of the previous example [DO NOT RUN IT]: -=-=-=-=-=-= points := -3.14 to: 3.14 by: 0.000001. g := RTGrapher new. d := RTData new. d connectColor: Color blue. d noDot. d points: points. d y: #sin. d x: #yourself. g add: d. g axisX numberOfTicks: 10; numberOfLabels: 5. g -=-=-=-=-=-= The script tries to build the same graph but with 6 280 001 points. Which obviously, is way too many. Instead, you can do something like: -=-=-=-=-=-= points := SortedCollection new. 1000 timesRepeat: [ points add: (-3.14 to: 3.14 by: 0.000001) atRandom ]. g := RTGrapher new. d := RTData new. d connectColor: Color blue. d noDot. d points: points. d y: #sin. d x: #yourself. g add: d. g axisX numberOfTicks: 10; numberOfLabels: 5. g -=-=-=-=-=-= Which only display the graph with 1000 points. Cheers, Alexandre
