The following can do:
x=findgen(100)/100.
xrange=[0.1,1]
!p.position=[0.2,0.2,0.8,0.8]
xticks=9 & xtickv=[0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0]
plot,x,sin(x*20),xstyle=9,ystyle=1,yrange=[-1,1],xrange=xran ge,xticks=xticks
,xtickv=xtickv
axis,xaxis=1,xrange=xrange,xticks=xticks,xtickname=string(1. /xtickv,format='
(f4.1)'),xstyle=1
end

Then period 2 is coressponded to frequency 0.5. But I hope
tickv=[10,9,8,7,6,5,4,3,2,1] for period axis. How to do then? Maybe '/xlog'
will be used, because log(period)=-log(frequency). But I failed to do that,
although I tried again and again.
