Coloring with coordinates.

Hi I have a some x data with upper and lower y data and wanted to color the enclosed section that is made.

Here is the code so far.

x_data = [3/8 4 8 16 30 50 100];
uppery = [100 100 100 85 60 30 10];
lowery = [100  95  80 50 25  5 0];

semilogx(x_data, uppery, x_data, lowery);

x_data = [3/8 4 8 16 30 50 100];
uppery = [100 100 100 85 60 30 10];
lowery = [100  95  80 50 25  5 0];

x = [x_data fliplr(x_data)] ; 
y = [uppery fliplr(lowery)] ; 

semilogx(x,y);
hold on
fill(10.^log10(x),y,'y')
