Dear Experts,

When using "plot" and "polygon", I can change the density and angle of the
shaded area lines when plotting is done in regular scale. It does not seem
to work in 'log' scale. Any suggestions would be highly appreciated!

below is an example:

plot(1:10,c(1:10)^2*20,log="y")
polygon(c(3:7,7:3),c((3:7)^2*20,c(7:3)^2*10),col='grey',angle=45,dens=30)

Warning message:
In polygon.fullhatch(xy$x[start:(end - 1)], xy$y[start:(end - 1)],  :
  cannot hatch with logarithmic scale active

Regards,
Santosh
