Hi Zhongyi,

I must confess I not understood completely what you need, but...

Tau<-seq(0.05,0.95,0.05);
Pi <- seq(0.19,0.01,-0.01);
par(cex.axis=0.8,ps=9,mar=c(1.5,1,0.5,1), oma=c(1,1,0.2,1) ,tck=-0.01);
plot(Tau,Pi, type='l', xlab="Tau",ylab="Pi",col=4, xaxt="n", yaxt="n");
axis(1,labels=F)
axis(1,line=-1, lwd=0)
axis(2,labels=F)
axis(2,line=-0.5, lwd=0)
mtext("x_txt",side=1, line=0.5)
mtext("y_txt",side=2, line=1.2)

cheers
