CONTOUR problem

HI~ everyone~ i use the contour pro to display a 2Darray named s11.
And I wrote it like this:

CONTOUR,s11,rangle,vangle,xrange=[0,180],yrange=[0,90],ytitle='Viewing
zenith angle',xtitle='Relative azimuth angle',/C_LABELS

But the xrange and yrange do not work and it only labeled on line in
the image , Any one see where the problem is ?

Thank you very much~

The whole program is like this if u want to see it:

rangle=findgen(180)
vangle=findgen(90)
y1=rangle*3.1415926*2/360

;print,sin(thta2)

y21=sin(y1)*sin(y2)

x12=sin(thta1)*cos(y1)
x22=sin(y1)*cos(y2)
y12=sin(thta1)*sin(y1)
y22=sin(y1)*sin(y2)

x13=sin(thta1)*cos(y1)
x23=sin(y1)*cos(y2)
y13=sin(thta1)*sin(y1)
y23=sin(y1)*sin(y2)

for i=0,179 do begin
for j=0,89 do begin
r1(i,j)=x10(i)*x20(j)+y10(i)*y20(j)+cos(y20(j))*co s(thta1)
r2(i,j)=x11(i)*x21(j)+y11(i)*y21(j)+cos(y21(j))*co s(thta2)
r3(i,j)=x12(i)*x22(j)+y12(i)*y22(j)+cos(y22(j))*co s(thta3)

nlevels=5
CONTOUR,s11,rangle,vangle,xrange=[0,180],yrange=[0,90],xstyle=1,ystyle=1,ytitle='Viewing
zenith angle',xtitle='Relative azimuth
angle',C_LABELS=replicate(1,nlevels)

To know how many levels there are (nlevels), you must set the LEVELS
keyword yourself., otherwise make nlevels big enough.

Thanks , it works. but the xrange still does not work......

Btw, how can I set the intervals of the contour ?
thanx

Set the [XY]Style keywords to 1 to force exact axis scaling.
This is, IMHO, almost always necessary when using the CONTOUR
command. You can find more information about the anemic
CONTOUR command here:

Sorry, another question....why i always get red as the back ground
color when i use this statement?

!P.background=255 i thought it should be white....

The quick answer would be:

device,decomposed=0
!P.background=255
CONTOUR,s11,rangle,vangle,xrange=[0,180],yrange=[0,90],color=0,xstyle=1,ystyle=1,ytitle='Viewing
zenith angle',xtitle='Relative azimuth angle',C_LABELS=replicate(1,10)

=> note the xstyle,ystyle and color keywords
