Here is one way:
load CountArray_A.mat
x = CountArray_A(:,1).';
y = CountArray_A(:,2);
figure();
graph = barh(x,y,'FaceColor',[1 0 0],'EdgeColor',[0 0 0]);
name = "saagagagasgadgadgadg" + newline + "ddsbds fbsfs sdbsdsz dhwh ddadgada adggdv"; % Added newline
legend(name,'Location','northeast','Orientation','horizontal') % Removed unnecessary cell
