Plot separate histograms.

Hi, I want to plot two separate histograms for the following data. A histogram having values more than zero from the column in the far right corner and another one when the value is zero. Any help is much appreciated. Thank you.

  St-1  St-2  St-3  Number
% Date  Temp  Temp  Temp  
% YYYYMMDD  [°C]  [°C]  [°C]  
        
20060301  17.6  18.8  20.2  1
20060302  17.4  18.3  19.3  2
20060303  17.7  18.6  18.5  2
20060304  18.5  17.8  19.7  0
20060305  16.5  17.8  17.9  0
20060306  17.6  18.4  18.4  1
20060307  18.1  21.6  19.9  2

Assuming this is a n x 5 matrix, the following commands will give you separate matrices based on your condition.

% x being your initial matrix
matrix_non_zero = x(x(:, 5) > 0, :);
matrix_zero = x(x(:, 5) == 0, :);

Now you can plot an histogram for these matrices based on your requirements.

Hi, thanks. I did the same thing. But I was wondering if it would be possible to implement a for loop for this problem?

MATLAB is optimized to work with the way I mentioned. Using loops is generally discouraged. :)
