You pointed out indeed a default in Grapher. We will fix this in the future⦠Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Well⦠Building the list of coordinate is not a big deal :-) { 5 . 1 . 2 . 5 } withIndexCollect: [ :v :index | v @ index ]

Hi Alex,
Thanks for your answer. I misunderstood RTStackedDataSet. To me, it does not do what the doc says ;-)
I want to do exactly that:
c := RTGrapher new. ds := RTDataSet new. ds dotShape color: Color red. ds points: {5@1 . 1@2 . 20@3 . 5@4 }. ds x: [ :e | e y ]. ds y: [ :e | e x ]. c add: ds. c axisX noDecimal. c axisY noDecimal. c build. c view inspect.
But I would like to not write by hand (or compute) the X values in the data set which are the indexes of the element.
Thanks,

This is something that is not really intuitive in Roassal. I am not sure whether this is a bug, but until now, we usually disable the labels on the X-axis.
So, your script should be -=-=-=-=-=-=-=-=-=-=-=-= b := RTGrapher new. ds := RTStackedDataSet new. ds dotShape color: Color red. ds points: #(5 1 20 5). ds y: #yourself. b add: ds. b axisX noLabel; noTick. b axisY noDecimal. b -=-=-=-=-=-=-=-=-=-=-=-= <Screen Shot 2015-06-16 at 5.37.44 PM.png>
If you need ticks and labels, you can simply do: -=-=-=-=-=-=-=-=-=-= b := RTGrapher new. ds := RTStackedDataSet new. ds barShape width: 10. ds barChartWithBarCenteredTitle: #yourself. ds points: #(5 1 20 5). ds y: #yourself. b add: ds. b axisX noLabel; noTick. b axisY noDecimal.
b -=-=-=-=-=-=-=-=-=-= <Screen Shot 2015-06-16 at 5.39.28 PM.png>
I hope this solves your problem.
Cheers, Alexandre

Hi,
The doc here [1] says: "Data points may be stacked, meaning that the index of the point in the collection is its X value."
When I use the same example as in the doc but with labels and ticks:
b := RTGrapher new. ds := RTStackedDataSet new. ds dotShape color: Color red. ds points: #(5 1 20 5). ds y: #yourself. b add: ds. b axisX noDecimal. b axisY noDecimal. b build. b view inspect
it seems that y values are not aligned on x ones (i.e. I would expect the first red point to be 1@5). Is it a bug or did I misunderstood something?
