connecting bargraph data points with a line

Hi all, I have been sratching my head for a couple of days to connect each of the data points I plotted on a bar graph. I have a repeated measures design where I would like to make a before-after comparison. In the currect graph I succeed in showing the presence or lack of group differences. But I would also like to show how each individual subject responded to the manipulation. So I would like to connect the subject 1 before data point to the subject 1 after data point. Any idea how I can achieve this? Below is my code. Thanks in advance for your advice.

% data1_nor_mean_band (band,:) & data2_nor_mean_band (band,:) are a 1x8 vectors

hs= superbar(a,'E',asem,'ErrorbarStyle', 'T');%barwitherr(astd,a);%superbar(a,'E',astd,'ErrorbarStyle', 'T');
hold on

 ax_detail=get(gca);
ahandle=get(gca,'Children');
Line1=ahandle(1,1);
Line1.Color= 'k';

Line2=ahandle(2,1);
Line2.Color=C(2,:); %[0 0 0];
Line2.Color='k'; %[0 0 0];


Bar1=ahandle(3,1);
Bar1.EdgeColor=  'k';% [ 0.90    0.55    0.55];%[1 0 0];
Bar1.FaceColor= 'none';%[1 0 0]


Bar2=ahandle(4,1);
Bar2.EdgeColor=   'k';% [0.62    0.76    0.84];% [0 0 0];

% PLOT DATA POINTS ON BARS

    % ax1(1,1) position of the bar graph desired
    % added to give the scatterplot a jitter
    hold on
end

    bp1(i,1)=plot(ax2(1,1)- (0.01*i),data1_nor_mean_band(band,i),'ko','Color','b','MarkerSize',6,'MarkerFaceColor','b');%C(2,:));
    hold on
end

Ah! I think I suceeded. Thanks for reading anyway. Below is my solution:

x = [get(bp1(1,1),'XData') get(bp2(1,1),'XData')];

y = [get(bp1(1,1),'YData') get(bp2(1,1),'YData')];

line(x,y,'Color','red','LineStyle','--')
