Bart chart absolute width

I create several bar charts during an optimization run in which i do not know the number of bars beforehand. I want all figures to be of the same size. The plots look quite nice, however, if there is only one bar in the figure, it creates a ugly bar chart. I would like to narrow the bar size in case there is one bar with probability 1 (happens quite often). In the attachment it is clearly visible what i mean.

Plot are created with the following code:

for i = 1:N_Locations

set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);

figure(4+ceil(i/9))

subplot(3,3,i-9*floor(i/9.01))

Rows = find(OrderSize_Empirical(:,1)==Locali(i));

bar(OrderSize_Empirical(Rows(1):Rows(end),3),'FaceColor', [45/255 0 84/255])

Ordersizes = num2cell(OrderSize_Empirical(Rows(1):Rows(end),2));

set(gca,'xticklabel',Ordersizes);

set(gca,'xtick',1:size(OrderSize_Empirical(Rows(1):Rows(end),2)));

str = strcat('Empirical order sizes at location: ',num2str(Locali(i)));

title(str);

xlabel('Order size')

ylabel('Probability')

end

The bar plot widths appear to scale according to the number of bars plotted.

The easiest way might simply be to cheat:

if numel(OrderSize_Empirical(Rows(1):Rows(end),3)) <= 1
    patch([-1 1 1 -1]*0.2, [0 0 1 1], [45/255 0 84/255])
    xlim([-1 1])
    set(gca, 'XTick',0, 'XTickLabel',1)
    title(str);
    xlabel('Order size')
    ylabel('Probability')
end

Experiment to get the result you want.
