Plotting genome scale values with Roassal

Hi,
I have a couple of Roassal questions regarding how to customize the plots of a genome metric known as GC skew, and how to scale the visualization to cover a (bacterial) genome scale data. I have isolated a Roassal sample code below from BioSmalltalk to show how I did an initial GC skew graphic: | b values ds | values := 'GGCTGCGTTCCCCTCAGTTAGCGCCTATCCTAAGCAGATCTGTAGTTAGTACTGTCTAAGCTTGTTAGACTACTCGGAACTTGCTGATATTAACCTTACCCCCGTCGAAACGCTTATTCCGCTTTGCTACTTCAAGCCCTGTAACATCTACTGTACTGACAAGGTTGCAGTAGCAATTGGCAAGGCTGTTTGGCATCTCAGATGACAGTTACCCGTGTTGCGCTCACCCGCAGCGACTCTCGGATACGTAACGCAGAAGACGTCTTCCGCGAGATTTGGGCGCGTCTGTCCACCTTCCCAGGTTGGCATTGGCAGAAGCTCTATCCGGCTTTGTTCCTCTAGCGGCTCCGCA' asDNASimpleSequence gcSkewInt. values := #(0 1 2 1 1 2 1 2 2 2 1 0 -1 -2 -2 -3 -3 -2 -2 -2 -2 -1 -2 -1 -2 -3 -3 -3 -3 -4 -5 -5 -5 -5 -4 -5 -5 -4 -4 -4 -5 -5 -4 -4 -4 -3 -3 -3 -3 -2 -2 -2 -3 -3 -2 -2 -3 -3 -3 -3 -2 -3 -3 -3 -2 -2 -2 -2 -1 -1 -2 -2 -2 -3 -3 -4 -3 -2 -2 -2 -3 -3 -3 -2 -3 -3 -2 -2 -2 -2 -2 -2 -2 -2 -3 -4 -4 -4 -4 -5 -6 -7 -8 -9 -8 -8 -9 -8 -8 -8 -8 -9 -8 -9 -9 -9 -9 -9 -9 -10 -11 -10 -11 -11 -11 -11 -10 -11 -11 -11 -12 -12 -12 -13 -13 -13 -12 -13 -14 -15 -15 -14 -14 -14 -14 -15 -15 -15 -16 -16 -16 -17 -17 -16 -16 -16 -17 -17 -16 -16 -17 -17 -17 -16 -15 -15 -15 -14 -15 -15 -14 -14 -14 -13 -14 -14 -14 -14 -14 -13 -12 -13 -13 -13 -12 -11 -12 -12 -11 -11 -11 -11 -10 -9 -10 -10 -10 -11 -11 -12 -12 -11 -11 -11 -10 -10 -11 -11 -10 -10 -10 -10 -11 -12 -13 -12 -12 -11 -11 -11 -10 -11 -10 -11 -11 -12 -12 -13 -14 -15 -14 -15 -15 -14 -15 -14 -14 -15 -15 -16 -16 -17 -16 -15 -15 -15 -15 -16 -15 -15 -15 -15 -16 -15 -16 -16 -15 -15 -15 -14 -14 -15 -14 -14 -15 -15 -15 -16 -17 -16 -17 -16 -16 -15 -15 -15 -15 -15 -14 -13 -12 -13 -12 -13 -12 -12 -13 -13 -12 -12 -13 -14 -14 -15 -16 -16 -16 -17 -18 -19 -19 -18 -17 -17 -17 -16 -15 -16 -16 -16 -16 -15 -14 -15 -15 -14 -14 -14 -13 -14 -14 -15 -15 -15 -15 -16 -17 -16 -15 -16 -16 -16 -16 -15 -15 -15 -16 -17 -17 -18 -18 -18 -17 -18 -17 -16 -17 -17 -18 -19 -18 -19 -19). b := RTGrapher new. b extent: 800 @ 500. ds := RTData new noDot; points: values; connectColor: Color red; yourself. b add: ds. b axisY minValue: values min; title: 'Skew'; color: Color black; noDecimal. b axisX numberOfTicks: 10; noDecimal; color: Color black; title: 'Position'. b open 1) You can see the result in the TR Morph.png attached file.

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.
