Hi,
Does anyone know how to place a legend (annotation) inside a draw
widget? The legend that I use is somehow like this:
mywindow = OBJ_NEW ( ' IDLgrWindow ' )
myview = OBJ_NEW ( ' IDLgrView ' )
itemNameArr = ['One', 'two']
myLegend = OBJ_NEW ( ' IDLgrLegend ' , itemNameArr, /
SHOW_OUTLINE)
myview->Add, myLegend
mywindow->Draw, myview
and I have a Widget_draw that contains my plots (curves):
dr_window = WIDGET_DRAW ( tlb , UVALUE= 'draw' )
I know that by " mywindow->Draw, myview " the legend appears in
separate window (like an image) but I couldn't find any way to place
it inside my plot window (the widget_draw).
Thank you

The IDLAstro routine is called legend, by the way.
