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')

Wouldn't that just be a bar plot of the two vectors instead? Why plotyy?

thanks for your reply. I need the 2 axis because there is about a factor of 100 between the 2 vectors and they also use different units so i need the 2 axis

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?

thanks dpb I have updated the initial question above. I will have to use the vectors above, I cannot modify unfortunately

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)
