set x values in bar3 in matlab

You can set the x-values for a bar3 plot in MATLAB by using the set function to modify the XData property of the plotted bars. Here's an example:

main.m
% Sample data
x = 1:5;
y = 1:6;
z = rand(5,6);

% Create a 3D bar plot
b = bar3(z);

% Set the x-values for the bars
for k = 1:numel(b)
    % Get the x-data for the current bar
    xdata = get(b(k), 'XData');
    % Modify the x-data to match the desired x-values
    xdata = xdata + (x(k) - xdata(1));
    % Update the bar with the new x-data
    set(b(k), 'XData', xdata);
end

% Add axis labels
xlabel('X');
ylabel('Y');
zlabel('Z');

In this example, we first create some sample data to plot. We then use the bar3 function to create a 3D bar plot of the z data. Next, we loop over each bar in the plot using the numel function to get the total number of bars. For each bar, we use the get function to retrieve the x-data (XData property) of the bar, and modify it to match the desired x value using simple algebra. We then use the set function to update the bar with the new x-data. Finally, we add axis labels to the plot.
