I have data for several histograms I am willing to plot like this one in attachenment using matlab. Is it possible in matlab of yes plese gauide
i have attached here 10*16 matrix data and on z axix i wanted to plot number of couts similar to that of verticle axis in 2d histogram plot

Ran in:
I understand that you want to plot a 3D Histogram from a matrix. For any histogram plotting, we need to decide on a bin size, that is the size of the smallest unit on one axis to be considered for calculating counts on the z axis. As mentioned in this example, the sample code for generating a 3D histogram for 30X1000 matrix, with random real numbers between -5 and 5, and a bin size of 0.5 is as follows
%generating random data
data = zeros(30,1000);
for k = 1:30
data(k, :) = rand(1) + rand(1)*randn(1000, 1);
end
%defining bins
bins = [-5:0.5:5];
counts = histc(data, bins, 2);
%plotting
hf = figure;
ha = axes;
hb = bar3(bins, counts.');
xlabel('split 1')
ylabel('bins');
zlabel('count');
In your case, the matrix size is 16X10. You can recheck your matrix once, considering that each row has identical values across columns. Assuming a range of -1 and 1, with a bin size of 0.1. We can generate the 3D Histogram as follows
data = readmatrix("data.txt");
edges = [-1:0.1:1];
counts = histc(data, edges, 2);
hf = figure;
ha = axes;
hb = bar3(edges, counts.');
xlabel('split 1')
ylabel('bins');
zlabel('count');
You can change the bin size and the range as per your requirements.

Thank you!@Asmit Singh
I have manged it similarly with the help of mathwork officials and your absolutly right that the data attached here is actully dummy one!
Thank you for your time efforts and suggetion!!
