Dear Heather
Are you sure? I have never seen nice or very nice graphical analysis
by excel. IDL stands for Interactive Data Language. There is no limit
in interpretation, analysis or visualisation of data by idl.
PRO wid_test
tab=CREATE_STRUCT(name='slice','location',0.0,$
'number',0L,$
'concentration',0.0,$
'dia', 0L,$
'vol',0.0)
b=WIDGET_BASE()
t=WIDGET_TABLE(b,value=tab,uname='tab')
WIDGET_CONTROL,b,/realize
FOR i=0,10 DO BEGIN
WAIT,1
new_tab={slice}
new_tab.location=5.5+i
new_tab.number=10+i
new_tab.concentration=3.7+i
new_tab.dia=1+i
new_tab.vol=2+i
tab=[tab,new_tab]
WIDGET_CONTROL,t,set_value=tab
WIDGET_CONTROL,t,ysize=N_ELEMENTS(tab)
WIDGET_CONTROL,t,set_value=tab
WIDGET_CONTROL,t,column_labels=TAG_NAMES(tab)
ENDFOR
result=STRING(tab.(0))+','+STRING(tab.(1))+','+$
STRING(tab.(2))+','+STRING(tab.(3))+','+$
STRING(tab.(4))
OPENW,lun,'file.csv',/GET_LUN
PRINTF,lun,result
FREE_LUN,lun
END

The table is quite new I believe only 3 years old. Most other widget
elements are known very well.
My example uses an arrayed structure, then the tabular column types
could be different. A comma separated list should be readable by excel
if it's not to long. There is a limit by 65534 lines for Excel.
All operation which you are known by clicks from ms software
could be simple commands in the script. Normally routines I wrote got no
interactive interface. Because if a user request has do be done by
someone
he or she all the time has to interact with the job the computer
normally could
do itself. Many of our routines can run with different data on several
computers
without an operator sitting behind a screen.
There are several ways to share input data with idl processes or idl
routines.
If you are interested in our idl library you'll get it from
