how to remove the gap between subsequent plots

Hello guys, I am trying to plot the a set of vectors (V) over of another set of vectors (O) in way similar to plotmatrix. I had a look on its source code at http://www-2.nersc.no/~even/matlab/toolbox/specgraph/plotmatrix.m but it was not very helpful. So, I decided to create my own version. I believe that I have nearly get there, but I miss two things. It is a figure of many subplots. See the picture: http://i289.photobucket.com/albums/ll232/veroulacs/untitled.png

1. How can I remove the "gaps" between the plots? I have deleted the X and Y TickLabels by using set(gca,'YTickLabel','') and set(gca,'YTickLabel','') but my guess is that there exists some other type of object or margin between each plot. I want to make the assembly more compact.
2. Although I specify the x and y axis range by using axis( [VARIABLES_LOWER(var) VARIABLES_UPPER(var) OBJECTIVES_LOWER(obj) OBJECTIVES_UPPER(obj)]); on EACH plot, matlab automatically uses different ticks for the axis, not the same ones with the aforementioned axis. I want the ticks to be set as the axis. E.g. plot (3,1), the range of xticks should be between 5500 and 6100

Any ideas/suggestions/recommendations are more than welcome and highly appreciated

Thanx for reading and your time C.T.

1. Create custom axes, e.g.:

 h1 = axes('Position',[0.1 0.1 0.4 0.4]);
 h2 = axes('Position',[0.1 0.5 0.4 0.4]);
 h3 = axes('Position',[0.5 0.5 0.4 0.4]);
 h4 = axes('Position',[0.5 0.1 0.4 0.4]);

2. Set your ticks manually, e.g.:

 set(h1,'XTickMode','manual');
 set(h1,'XTick',[some_value some_larger_value]);,

For more information, please read the documentation on "Axes" and "Axes Properties".
