my graph is not evenly spaced evrything clustered in matlab

To plot a graph with unevenly spaced data points in MATLAB and prevent them from being clustered, you can use the plot function with the scatter option along with specifying the x-coordinates explicitly. Here's an example:

main.m
x = [1, 3, 5, 8, 12]; % x-coordinates of the data points
y = [5, 3, 7, 2, 9]; % y-coordinates of the data points

scatter(x, y, 'filled'); % Plot the points with scatter plot

% Label the axes
xlabel('X-axis');
ylabel('Y-axis');

% Set grid
grid on;
250 chars
12 lines

In this code snippet, x and y contain the x-coordinates and y-coordinates of the data points, respectively. By using scatter, you can plot the data points on the graph without connecting them with lines. This will prevent them from being clustered even if they are not evenly spaced along the x-axis.

Remember to adjust the x and y vectors according to your actual data points.
