Plotting bar graph for loop values

I am trying to make a barplot of the values in vector's 'count_gn', 'count_bn', 'count_hn' and 'count_ar' as a seperate subplots. I tried using 'bar' function for the purpose. But i am not seeing any barplots.

Can anyone suggest a method to do seperate barplots for the values in the vector 'count_gn', 'count_bn', 'count_hn' and 'count_ar' ?

Any help to solve this will be appreciated.

a = smoothed_final_plot_mat(1:end-2033,3:end-2);
np = (size(a,2)-1)/2;        % number of particles
t = a(2:end,1);
arena_image = imread('arena_pic_gn_top.png');
subplot(1,2,1)
h1 = axes ;
cc = hsv(np);
image('XData',[0 6900],'YData',[0 5000],'CData',arena_image) ; % set your limits
set(h1,'YDir','normal');
dim = [0.79, 0.825, 0.2, 0.1];
annotation('textbox',dim);
t1 = uicontrol('Style','text','String','Select a data set.','Position',[1550 790 300 80],'FontSize',13,'HorizontalAlignment','left');
ax = gca;
ax.YDir = 'reverse';
axis([0 6900 0 5000])
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0, 0.04, 1, 0.96]);
h = zeros(1,np);  
for ii = 2:25:size(a,1)
    ax.Position(3) = 0.65; 
    k = 0;
    t = a(ii,1);   
    count_gn(ii,1) = rowsum_for_ants_in_gdnest_matrix(ii);  %#ok<SAGROW>
    count_bn(ii,1) = rowsum_for_ants_in_bdnest_matrix(ii);  %#ok<SAGROW>
    count_hn(ii,1) = rowsum_for_ants_in_arena_except_homenest(ii);  %#ok<SAGROW>
    count_ar(ii,1) = rowsum_for_ants_in_field(ii);  %#ok<SAGROW>
    hold on
    for jj = 2:2:np*2             % ant handles
        x = a(ii,jj);
        y = a(ii,jj+1);
        k = k + 1;

I randomized some data and got a barchart,

so may be the problem is with your data

try checking if there are NaN value in there, if you are summing them, the default behaviour of sum is to return NaN when it sums NaN with the numbers.

If so, you can try using

x = [magic(3) nan(3,1)];
sum(x, 2)
sum(x, 2, 'omitnan')

ans =

   NaN
   NaN
   NaN


ans =

    15
    15
    15

Hi, i checked the data throughly, there is no NaN in the data. Also when i try to use 'bar' one of the axis always keeps on moving.
