readtable will do well to read in the file
converting it to categorical will make it easier to make a bar out of
reordercats will help for changing the order on the x axis (I did them by the height of the bars, but you could do them by whatever order you like)
figure(1)
t=readtable('lh_text.txt');
t.Var1=categorical(t.Var1);
bar(t.Var1, t.Var2)
% if you want it in order of biggest to smallest bar:
figure(2)
[~,sortind] = sort(t.Var2,'descend');
t.Var1=reordercats(t.Var1,sortind);
bar(t.Var1, t.Var2)
