create a x y scatterplot with interconnected points and red line in matlab

To create a scatter plot with interconnected points and a red line in Matlab, you can use the plot and scatter functions.

Here is an example code:

main.m
% sample data
x = [1, 2, 3, 4, 5];
y = [10, 20, 30, 40, 50];

% plot scatter plot
scatter(x, y);

hold on % to plot the line on the same plot

% plot a line connecting the points
plot(x, y, 'r-');

% add title and labels
title('Scatter plot with a red line');
xlabel('X axis');
ylabel('Y axis');

17 lines

The scatter function is used to plot the individual points, while the plot function is used to draw the connecting line between the points. The letter 'r' in 'r-' stands for "red", and the dash means that the line should be solid.

You can adjust the data (x and y) and the plot settings to your own needs.
