||Using IDL, I want to have a color image, using tvscl. How do I put axes on the
||image? (axes should be on edge of image, to indicate location).
||Thus, for an image of 450*480 , I want to put an axis, with the
||x axis going linearly from 0 to 450, and the y axis going in log scale from

Regarding this, First of all, keep track of the position of the Bottom half of the
image is w.r.t the device (ex:tvscl,image,xpos,ypos)

Then typing:
contour,image,xx,yy,pos=[xstart,ystart,xfin,yfin],/nodata,/d evice,/noerase $
,YST=1,XST=1,TICKLEN=-0.03

you generate your own xx & yy array as you want. POS is array for the position of the
contour. The rest of the keywords are the reference book (P.2-2 of ver 3.5)
Try it out, It worked for me!

Good luck

Fern..
