MATLAB: How can i plot

plotting

I have on matrix such as A=[ 2.8866 2.5708 2.9381 2.6234 2.7873 2.8535 3.5818 4.1817 3.6535 4.6312 4.2028 4.4109 3.6008 4.4279 3.8003 3.7995 4.3140 4.4061 5.2382 4.5073 4.2002 3.9283 3.1146 3.0891]. A is one matrix 24*1.each element of matrix is value of losses for each hour a day.for example for hour between 0 ,1 losses is 2.8866 for hour between 1 ,2 the losses is 2.5708. how can i plot losses for 24 hours?
thanks

Try this: 
A=[2.8866    2.5708    2.9381    2.6234    2.7873    2.8535    3.5818    4.1817    3.6535    4.6312    4.2028    4.4109  3.6008    4.4279    3.8003    3.7995    4.3140    4.4061    5.2382    4.5073    4.2002    3.9283    3.1146    3.0891];
Hours = 0.5:23.5;
figure
stairs(Hours, A)
axis([0.5  23.5    0  6])
set(gca, 'XTick',Hours, 'XTickLabel',(0:23))
grid
xlabel('Hours')
ylabel('Loss')
