I want to draw a bar graph in MATLAB that represent players versus years won. For instance,
_
_____________________________________
Country Years won
______________________________________
US 2002, 2005
Canada 2012, 2013
Belgium 2003, 2004,2011, 2017
Hungary 2001, 2015, 2016
How can I draw the bar of this data values in MATLAB? I was wondering if someone could help me?

I would like to know the problem of the following codes to generate the bar graphs. Moreover, I need the years to appear on the graph. Anyone help. Thanks.
Names = {'US','Canada','Belgium','Hungary'};
YearsWon = {[2002, 2005],[2012, 2013],...
[2003, 2004,2011, 2017],[2001, 2015, 2016]};
set(gca, 'YTickLabel', Names,...
'XTick',2001:2017);
xlabel('Years Won');ylabel('Country Name')

Hailemariam - this seems like homework, so take a look at the Create Bar Graph with Categorical Data example from MATLAB bar graph. Presumably you will want you x-axis to have labels using each of the four countries from above. This example will show you how to do that.

But how does the bar "work" for the US as they didn't win in 2003 and 2004? Or are you looking more for a way to fill in the spaces (along the axes) that correspond to wins for the country?
If the latter, then you can try something like
Names = {'US','Canada','Belgium','Hungary'};
YearsWon = {[2002, 2005],[2012, 2013],...
[2003, 2004,2011, 2017],[2001, 2015, 2016]};
set(gca, 'YTick',1:4,'YTickLabel', Names, 'XTick',2001:2017);
ylim(gca,[0 5]);
xlim(gca,[2000 2018]);
hold on;
countryColours = {'r', 'b', 'g', 'm'};
for u=1:length(Names)
countryWins = YearsWon{u};
for v=1:length(countryWins)
winYear = countryWins(v);
fill([winYear winYear+1 winYear+1 winYear], ...
[u u u+1 u+1],countryColours{u});
end
end
axis(gca, 'image');
In the above, we loop through all of the countries and use fill to create a square for the country at the win year (a different colour is used for each country).
