boxplot median, position refinement

Hi I am trying to plot the tolerance spread between 3 different methods for two different company drawings as outlined in the picture. I like the boxes to be closer together and wider. I tried position but it didnt work. Apparently, boxplot creates the median line so is always in the middle. I would like the mean for each box and connect the mean points with a line

thanks

A=[...
   0.0189    0.00839   0.01542     NaN   0.217   0.1865   0.1985;
   -0.0303   -0.01979  -0.02682   NaN  0.107    0.1375   0.1255; ];
  figure('color', 'w');
c = colormap(lines(3));
 C = [c; ones(1,3); c];  % this is the trick for coloring boxes
boxplot(A, 'color', C, 'plotstyle', 'compact', ...
    'labels', {'','STACK A','','','','STACK F',''}); 
hold on;
for ii = 1:3
    plot('color', c(ii,:));
end
