How to change space between bars in a bar graph and the y-axis/edges of the graph?

I'm trying to change the distance between the bars of my graph and the vertical edges of the graph so there is little to no space (the bars touch the y-axis). How can I do this? My current code is:

data = [1, 2, 3; 1, 2, 3; 1, 2, 3];

labels = ["a", "b", "c"];
graph = bar(pubs,'stacked');
ylabel("Number of Publications");
xticks(1:length(data));
xticklabels(labels);
xtickangle(45);
set(gcf, 'Position', [0,0,1000,400]);

data = [1, 2, 3; 1, 2, 3; 1, 2, 3];

labels = ["a", "b", "c"];
graph = bar(data,'stacked');
ylabel("Number of Publications");
xticks(1:length(data));
xticklabels(labels);
xtickangle(45);
set(gcf, 'Position', [0,0,1000,400]);
axis tight % <==== add this line

Two questions regarding this:

1. Is it possible to only mage one of the axes tight (say x)?
2. Is it possible to somehow apply this to string (categorical) x-axis too?

Thank you.
