I want same distance between each bars. Now the distance between 1 and 10 is closer than that between 10 and 50 or 50 and 100.

How can I edit the graph?

You will need to turn your System Size values into categoricals. You haven't shared your data, so here's a simple example.

% What you currently have

systemSize = ([ones(4200,1);10*ones(500,1);50*ones(100,1);100*ones(50,1)]);

histogram(systemSize)

xticks([1 10 50 100])

% With x data type as categoricals

catSystemSize = categorical(systemSize);

histogram(catSystemSize)

num_simulations = 10000;

system_sizes = [1, 10, 50, 100]; % System sizes in MW

% Define SOEC parameters

capex_system_SOEC_min = 2800; % Minimum Capex for the system in euro/kW

capex_system_SOEC_max = 5600; % Maximum Capex for the system in euro/kW

capex_stack_SOEC_percentage = 0.5; % Percentage of Capex system for the stack

% Generate SOEC Capex values

capex_system_SOEC_values = linspace(capex_system_SOEC_min, capex_system_SOEC_max, numel(system_sizes));

capex_stack_SOEC_values = capex_stack_SOEC_percentage * capex_system_SOEC_values;

capex_SOEC_total_values = (capex_system_SOEC_values + capex_stack_SOEC_values) ./ system_sizes;

% Define PEM parameters

capex_system_PEM_min = 1100; % Minimum Capex for the system in euro/kW

capex_system_PEM_max = 1800; % Maximum Capex for the system in euro/kW

capex_stack_PEM_percentage = 0.35; % Percentage of Capex system for the stack

% Generate PEM Capex values

capex_system_PEM_values = linspace(capex_system_PEM_min, capex_system_PEM_max, numel(system_sizes));

capex_stack_PEM_values = capex_stack_PEM_percentage * capex_system_PEM_values;

capex_PEM_total_values = (capex_system_PEM_values + capex_stack_PEM_values) ./ system_sizes;

% Define AEC parameters

capex_system_AEC_min = 500; % Minimum Capex for the system in euro/kW

capex_system_AEC_max = 1400; % Maximum Capex for the system in euro/kW

capex_stack_AEC_percentage = 0.35; % Percentage of Capex system for the stack

% Generate AEC Capex values

capex_system_AEC_values = linspace(capex_system_AEC_min, capex_system_AEC_max, numel(system_sizes));

capex_stack_AEC_values = capex_stack_AEC_percentage * capex_system_AEC_values;

capex_AEC_total_values = (capex_system_AEC_values + capex_stack_AEC_values) ./ system_sizes;

% Combine all Capex values for each technology

all_capex_values = [capex_SOEC_total_values; capex_PEM_total_values; capex_AEC_total_values];

% Create a grouped bar graph

figure;

bar(system_sizes, all_capex_values, 'grouped');

xlabel('System Size (MW)');

ylabel('Average Capex (euro/MW)');

title('Comparison of Capex for Different Technologies and System Sizes');

legend({'SOEC', 'PEM', 'AEC'}, 'Location', 'Northwest');

grid on;

It's my data set.

Your code is fine, except that you still need to convert your X values to categoricals. This allows the x position to be set by group number instead of numeric value.

This is the only line of code that needs to change.

bar(categorical(system_sizes), all_capex_values, 'grouped');
