Hi Joseph,
To display user-defined data in a plot and show the minimum and maximum values in MATLAB, follow these steps:
- Load or define your dataset.
- Calculate the min and max values using "min()" and "max()".
- Plot the data using "plot()".
- Use "text()" or "annotation()" to display the values on the plot.
Example Code:
% Sample dataset
x = 1:10;
y = [3, 5, 2, 8, 6, 7, 4, 9, 1, 10];
% Find max and min values
max_val = max(y);
min_val = min(y);
% Plot the data
figure;
plot(x, y, '-o', 'LineWidth', 2);
xlabel('X-axis');
ylabel('Y-axis');
title('User-Defined Data Plot');
grid on;
% Display max and min values on the right side of the plot
text(max(x) + 0.1, max_val, sprintf('Max: %.2f', max_val), 'FontSize', 12, 'Color', 'red');
text(max(x) + 0.1, min_val, sprintf('Min: %.2f', min_val), 'FontSize', 12, 'Color', 'blue');
You can refer to the below MATLAB documentation to read more about this functions:
- text(): Add Text to Chart
- annotation(): annotation - Create annotations

I hope this helps!
