How to make a graph in matlab from a dataset?

You can ignore the first couple parts of the program as this is just a set up, you can go to the part where it gives you the first choice. So what im trying to do is make a bar graph of fifa teams and the amount of points that they have. The dataset is a 50x9 matrix. Im trying to have it graph all the rows (which is the amount of points) of column 4. However I keep experiencing an error. Ive never done bar graphs so I dont know how this work. I appreciate any inputs that you guys could give me.

fprintf('*loading dataset...\n');
fprintf('*analyzing dataset...\n');
data=dataset('File', 'thegrid2.txt', 'Delimiter', ',');
[rows cols] = size(data);

choice= menu('What would you like to see master?:', 'Graph 1', 'Graph 2', 'Graph 3', 'OR Graph 4')

if choice== 1
    x= 1:1:50;
    y= data(1:rows, cols-5);
    bar(x,y)
    title([ 'Countries vs. the amount of points: '])
    set(gca, 'Xtick', 1:1:50);
    set(gca,'XTickLabel', {'ESP','GER','ARG','CRO','POR','COL','ENG','ITA','NED','ECU','RUS','CIV','GRE','MEX','SUI','BEL','URU','FRA','BRA','DEN','BIH','GHA','CHI','SWE','CZE','MLI','MNE','USA','JPN','NOR','NGA','PER','HUN','ROU','ALG','VEN','UKR','PAN','IRL','SRB','TUN','KOR','PAR','TUR','ZAM','AUS','CRC','ALB','WAL','BFA'});
end

First I'd plot using barh and not bar if you have 50 (!) labels to plot. Second, if you need to plot only the 4th column, use, y= data(:,4);. For example:

data=rand(50,5);
x= 1:1:50;
y= data(:,4);
barh(x,y)
title([ 'Countries vs. the amount of points: '])
set(gca, 'Ytick', 1:1:50);
set(gca,'YTickLabel', {'ESP','GER','ARG','CRO','POR','COL','ENG','ITA','NED','ECU','RUS','CIV','GRE','MEX','SUI','BEL','URU','FRA','BRA','DEN','BIH','GHA','CHI','SWE','CZE','MLI','MNE','USA','JPN','NOR','NGA','PER','HUN','ROU','ALG','VEN','UKR','PAN','IRL','SRB','TUN','KOR','PAR','TUR','ZAM','AUS','CRC','ALB','WAL','BFA'});
ylim([0 51])
