double y axis bar chart to have bars next to each other

hi I have plotted a double y axis bar chart with the code below. It seems that the bars are overlaying. I am trying to get the bars so that they are next to each other on the same x position
Any help would be appreciated!
Wind_monthly_speed = [4.76 3.99 3.43 3.68 5.71 7.09 5.56 5.43 5.4 4.9 3.88 4.53];
Solar_monthly = [5.87 6.52 6.99 6.45 5.6 4.84 5.17 5.66 5.85 5.9 5.29 5.41];
month = 1:1:12;
average_monthly_wind_density = 1.2;
wind_monthly_power = 0.5*average_monthly_wind_density.*(Wind_monthly_speed.^3);
figure;
x1 = 1:12;
y1 = wind_monthly_power;
y2 = Solar_monthly;
plotyy(x1,y1,x1,y2,'bar','bar')

That'll end up scaling them grossly anyway, why not simply multiply the one by 100 and annotate it to note the change?
How about pasting about half your data for somebody to play with?

Well, I think it's much more informative as
bar(x1', [y1' y2'])
but suit yourself. As a starting point try
ha=plotyy(x1-0.5,y1,x1+0.5,y2,'bar','bar');
set(ha,'xlim',[-1 14])
set(ha,'xtick',1:12)
Then get the handles of the bar objects and modify colors and width to enhance visibility, etc., etc., etc., ... as desired
ADDENDUM:
Rather than use +/-0.5, try +/-0.2 save the additional handles from the plotyy() call--
[hyy,hl,ho]=plotyy(x1-0.2,y1,x1+0.2,y2,'bar','bar');
set(hyy,'xlim',[-1 14],'xtick',1:12)
set(ho,'barwidth',0.4)
set(hl,'facecolor','r','barwidth',0.4)
