I replied to this in private e-mail to Ralph, but haven't heard anything
back from him.
For the rest of you, I think the problem is that his Z-buffer window
is not the same size as his graphics display window. There is nothing
wrong with using XYOUTS in the Z-buffer. I think when he transfers
the "image" from the Z buffer into his graphics window he is clipping
the title.
I suggested he try this:
thisDevice = !D.Name
SET_PLOT, 'Z'
DEVICE,SET_RESOLUTION=[RES_PLOT_X,RES_PLOT_Y]
!Y.OMARGIN=[2, 10]
!P.MULTI=[0,MULTI_PLOT_X,MULTI_PLOT_Y]
for i=5L,FIELD+4 do plot,ti,r(i,*),background=255, color=0,min_value=-998
XYOUTS, 0.5, 0.95, ALIGN=0.5, CHARSIZE=2.0,/NORMAL,STATION_NAME
a = TVRD()
SET_PLOT, thisDevice
WINDOW, XSIZE=RES_PLOT_X, YSIZE=RES_PLOT_Y
TV, a
This kind of code works in the Z-buffer and on the display for me.
Would like to hear the result!
