How to save a MATLAB created by bar function in a right size .pdf?

I save a graphic as .pdf format, but matlab will produce an A4 size to put this small picture in the middle of this A4 size pdf. The problem comes when I import them into my LaTeX file, i only need the picture size, not the whole A4 pdf size. Could anyone tell how to solve this problem?
This is my code
function DisplayGeneral(Conversational,Background,...
Interactive,Streaming,...
NameFunctions)
max1= max(Conversational(1,:));
max2=max(Background(1,:));
max3=max(Interactive(1,:));
max4=max(Streaming(1,:));
MAX=max(max1, max(max2,max(max3,max4)) );
% This will produce 4 groups of 3 different colored bars
x = [1 2 3 4];
y = [Conversational ;Background; Interactive ;Streaming];
Bar = bar(x,y); % h will have 3 handles, one for each color of bars
% set 3 display names for the 3 handles
%xtips1 = Bar(1).XEndPoints;
NameFunctions=cellstr(NameFunctions);
set(Bar, {'DisplayName'}, NameFunctions');
% Legend will show names for each color
legend() ;
somenames={'Conversational','Background','Interactive','Streaming'};
set(gca,'xticklabel',somenames)
set(gcf, 'Position', [100, 100, 800, 450]);
ylabel('Rank Reversal Ratio [%]')
xlabel('Traffic classes')
ylim([0 MAX+30]);
%text(xtips1,ytips1,string( ) ,'HorizontalAlignment','center','VerticalAlignment','bottom')
opts = {'VerticalAlign','middle', 'HorizontalAlign','left', ...
'FontSize',8, 'Rotation',90};
%title('')
for k1 = 1:size(Conversational,2)
ctr(k1,:) = bsxfun(@plus, Bar(k1).XData, Bar(k1).XOffset'); % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
ydt(k1,:) = Bar(k1).YData; % Individual Bar Heights
end
for k1 = 1:size(ctr,2)
format short
text(ctr(:,k1), ydt(:,k1), sprintfc('%.1f',ydt(:,k1)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom')
end
end
