Hi,
It is an error in the documentation. If you check the C version of the same
function it does not returns x,y, it actually receives x,y as parameters.
Best,Scuri

Dear all,
I've been working yesterday with iupPlot / Lua : what i want to do is to add
points with mouse (i could do this with plotbutton_cb) and, when i click on an
existing sample, to move it on the graph with mouse. I'm able to find the point
with the plot:FindSample(), and to select it isn't a problem -
plot:SetSampleSelection(). Even having mouse values isn't a problem with
plotmotion_cb. The problem is that i can't find a way to change the sample
coordinates : even the plot:SetSample() function doesn't work for me (and i
don't really understand why this function doesn't take x and y points as input
arguments).Is this function designed for that purpose ? Or is there another way
? Maybe having direct access on the Dataset Table could be great, but i don't
find neither a way to change coordinates in the dataset : the IupPlot page
online only talks about DS_REMOVE, or DS_COUNT, but there is no DS_EDIT or
something like that.
Any help would be great
Also, this Plot seems really powerfull, "bravo" for this beatiful work, and
thanks a lot.
Johann
