how to change colour of dots on graph in matlab to red in matlab

To change the color of the dots on a graph in MATLAB, you can use the plot function with the '.' specifier for the marker style, and specify the color using the 'MarkerFaceColor' parameter.

Here's an example:

main.m
x = 1:10;  % x values
y = x.^2;  % y values

plot(x, y, '.', 'MarkerFaceColor', 'red')
87 chars
5 lines

In this code, the plot function is used to create a scatter plot with red dots. The . specifier sets the marker style to dots, and the 'MarkerFaceColor' parameter sets the color to red.

You can modify this code according to your specific data and requirements.
