Folks,
I have some function graphics code that produces a box axes on a map.
Because this involves a lot of "after the fact" manipulation, I usually
turn window refreshing off so the user doesn't have to see all the
machinations. But, the window refresh has seemingly gone South in IDL
8.2.3.
Here is an example program. It works perfectly until you set the REFRESH
keyword. Then, you just see a big cross in the graphics window. :-(
;***********************************************
PRO Window_Refresh_Bug, Refresh=refresh
win = Window()
IF Keyword_Set(refresh) THEN win.refresh, /Disable
mp = Map('Equirectangular', CENTER_LONGITUDE=180, $
BOX_AXES=1, GRID_LATITUDE = 30, GRID_LONGITUDE = 45, $
LABEL_POSITION=0, LIMIT=[-89.99, 0, 89.99, 360], CURRENT=win)
mp['Latitudes'].label_angle=90
mp['Longitudes'].label_angle=0
grid = MapGrid( $
LONGITUDE_MIN=0, LONGITUDE_MAX=360, $
LATITUDE_MIN=-90, LATITUDE_MAX=90, $
GRID_LONGITUDE=45, GRID_LATITUDE=30, $
LABEL_POSITION=1, CURRENT=win)
FOREACH g,grid.latitudes DO g.label_angle=270
FOREACH g,grid.longitudes DO g.label_angle=0
c = MapContinents(Color=!Color.red)
IF Keyword_Set(refresh) THEN win.refresh
END
;***********************************************
Cheers,
David

If you manually push the third button from the left in the window, you get the right plot!
Very strange.

Works great. Thanks, Mark!

Great, thanks for quick fixes! By the way, will these fixes be collected
somewhere, besides the next release?

You're welcome, Mike & David! I'm planning a blog post with a zip file overlay, but I'd like to wait to see if the PDF/EPS issue mentioned in another thread has a PRO code fix.
