Surendar,
I'm not aware of a simple and elegant solution, i.e. without doing
everything by yourself. However, the following short procedure might
serve as a starting point, albeit far from being mature. . I needed it
once, and it was OK for my purposes.

Every order of magnitude is labeled, which causes space problems if the
data range is more than 10 orders of magnitude or so. Then the number of
'tickVals' has to be reduced

Cheers,
Markus

PRO logPlot, x,y

;**** Normal wave ticks

xc=!x.crange & yc=!y.crange

;**** self-made ticks
ytickVals=indgen(yc(1)-yc(0)+1)+yc(0)
yticknames='10!U'+string(ytickVals, form='(I2)')+'!N'

xtickVals=indgen(xc(1)-xc(0)+1)+xc(0)
xticknames='10!U'+string(xtickVals, form='(I2)')+'!N'

plot_oo, x,y, psym=-2, xrange=10.^xc, yrange=10.^yc,$
ytickname=yticknames, ytickv=10.^ytickVals,
yticks=N_ELEMENTS(ytickVals)-1,$
xtickname=xticknames, xtickv=10.^xtickVals,
xticks=N_ELEMENTS(xtickVals)-1
