Plotyy - overlapping bars and horizontal lines

Good Afternoon,

I am trying to plot some data in a bar chart but I require two y axis for scale reasons and am thus using plotyy. I have come across two problems though. 1. my bars are overlapping, I have been digging around for solutions and have found one that separates them, but it still looks messy, it isn't uniform across all the bars, is there another way? 2. I have plotted a horizontal line from y1 across the plot, but I need to also plot a separate horizontal line from the y2 axis, I'm a bit stumped as to how I do this, I did not indicate y1 when I plotted the first line.

% Variables

offset = (X(2)-X(1))/8;

width = (X(2)-X(1))/4;

% Plot

[aX, h1, h2] = plotyy(X-offset,y1,X+offset,y2, @(X,y) bar(X,y,width), @(X,y) bar(X,y,width));

set(aX(1),'YLim',[0 23])

set(aX(1),'YTick',[0:1:23])

set(aX(2),'YLim',[0 25.25])

set(aX(2),'YTick',[0:1:25.25])

set(aX(1),'box','off')

set(aX(1),'xlim',[0 52]);

set(aX(1),'Xtick',[0:1:51])

set(aX(2),'xlim',[0 51]);

set(aX(2),'Xtick',[0:1:51])

set(h1,'FaceColor','red');

set(h2,'FaceColor','blue');

hold on

plot(get(gca,'xlim'), [ten ten]);

hold off
