I am looking for info on how to use color tables by using a varying array
for colors. I am using colored boxes inside a loop. I need the color to
change according to the array values. ( I am drawing a histogram) I do not
want to list the color number. That is the only way it has worked for me
so far. Please if anyone has an idea email me back at
aothman@magnus.acs.ohio-state.edu.
the following is the relevent code. Thanks Ahlem...
+++++++
;;;
; testing color this time
;;;
rcolor = intarr(7)
gcolor = intarr(7)
bcolor = intarr(7)
rcolor(0) = 0
gcolor(0) = 0
bcolor(0) = 0
rcolor(1) = 255
gcolor(1) = 0
bcolor(1) = 0
rcolor(2) = 0
gcolor(2) = 255
bcolor(2) = 0
rcolor(3) = 0
gcolor(3) = 0
bcolor(3) = 255
rcolor(4) = 180
gcolor(4) = 64
bcolor(4) = 0
rcolor(5) = 64
gcolor(5) = 100
bcolor(5) = 200
rcolor(6) = 200
gcolor(6) = 0
bcolor(6) = 200
tvlct, rcolor, gcolor, bcolor ;;;;;;;;;
xyouts,360,yannot,legnd(dhrs), size = .5,color=1; I want to use an array here
; instead of color=1
;;;;;;;;;
for dsctr=0,n_elements(xval)-2 do $
box, xval(dsctr)+xoff,minval, $
xval(dsctr)+xoff+del, $
allpts(dsctr,dhrs), $
3
;colors(dhrs)
