Thanks for the quick answer, it now works as expected. I updated to a clean pharo 4 image and loaded roassal2 again (my previous image was just 2 months old). I had to change the ConfigurationOfGlamourCore to point from version 1.2.14 to version 1.2.10 of rubrick (don't know what rubrick is but changing the version allowed loading everything).
Still some things don't work as expected: export to svg and png in inspector. pngs are exported with the wrong viewport, svg are distorted, like with the old version.
As for the code, just copy-pasted from the docs in agilevisualization.com <http://agilevisualization.com/> or examples in image can't remember exactly though. I took them 2 or 3 months ago, but these same examples seem to be up-to-date now in both places.
Cheers

First of all, RTGrapherBuilder has been obsoleted. Use RTGrapher instead. I guess this is a problem with rounding with RTGrapherBuilder. With RTGrapher, I do not see this behavior.
For example:
-=-=-=-=-=-=-=-=-=-=-=-= events := { 10.0 @ 1.0. 9.0 @ 2.0. 8.0 @ 3.0. 7.0 @ 4.0. 6.0 @ 5.0. 5.0 @ 6.0. 4.0 @ 7.0. 3.0 @ 8.0. 2.0 @ 9.0. 1.0 @ 10.0. 0.0 @ 11.0}.
b := RTGrapher new. b extent: 400 @ 200.
ds := RTDataSet new. ds dotShape circle color: Color red. ds interaction fixedPopupText: [ :e | e printString ].
ds points: events. ds connectColor: Color blue. ds x: [ :e | e y ]. ds y: [ :e | e x ]. b add: ds. b axisX noTick; noLabel. b axisY noTick; noLabel. b build.
b view add: ((RTLine new width: 0.02; color: Color yellow) edgeFrom: b view elements fifth to: b view elements last). b view -=-=-=-=-=-=-=-=-=-=-=-=
A deep zoom-in shows everything is okay: <Screen Shot 2015-06-14 at 9.53.15 AM.png>

Hi guys, I'm drawing a chart with roassal2 and just discovered that lines are not being drawn exactly as expected. Maybe this is a known problem? I'm running on a few months old pharo4beta image, in linux. Here I attach a screenshot corresponding to the code below. There are more evident examples but this one is easier to debug as it is a straight line made of many segments (zooming a bit you'll see the thin reference line and notice the blue line "bends"). Thanks for reading!
Cheers, Javier
