Hi all,
At first I was kinda embarrassed to ask this but after spending my
complete day at finding a solution which appearantly I didn't find, I
don't know if the embarrassement would be fair :)
Problem: I want to draw an IDLgrPlot, with some axisses in my main
program. I have an array of [x,y] containing the data. How call the plot
in the following way:
------------------------------------------------------------ ---------
info.Scene = Obj_New('IDLgrScene')
info.View = Obj_New('IDLgrView', VIEWPLANE_RECT =
[0,0,info.xsize_widget, info.ysize_widget], /DOUBLE)
info.Model = Obj_New('IDLgrModel')
info.Scene->Add, info.View
info.View->Add, info.Model
info.Plot = obj_new('IDLgrPlot',[xData,yData])
info.View->SetProperty, Color=[0,0,0]
info.Plot->SetProperty, Color=[255,255,255]
info.Model->Add, info.Plot
(*info.ptrDrawWidget)->Draw, info.View
(*info.ptrDrawWidget)->Draw, info.Scene
--------------------------------------------------------

============================================================ =============
Now, when I execute this code, I don't get what I want. I get some
strange lines, of which you can view the result at
http://sophorus.mine.nu/idlgrplot_weird.jpg.
When I call iPlot just with the data set, I get exactly what I want.
That is, the figure is as it should be,but I need it in my program (no
ext. window) and need to draw additional things on it.
Now why isn't this working with IDLgrPlot? Appearantly I'm missing
something crucial :) but google nor davids site (about the resources I
use for getting to know what can and what can't be done :P) seem to help
me in this one.
Or, of course...I just can't search hehe :)
Who can help me? Thnx in advance!
