Line styles, markers, and colors in MATLAB - Mini Project: Build & Apply

Line styles, markers, and colors

📖 Scenario: You are creating a simple MATLAB plot to visualize data points with different line styles, markers, and colors. This helps make the graph clearer and more visually appealing.

🎯 Goal: Build a MATLAB script that plots a line with specific line style, marker, and color settings.

📋 What You'll Learn

Create a vector of x values

Create a vector of y values

Define a line style, marker, and color

Plot the data using the defined style, marker, and color

Display the plot

💡 Why This Matters

🌍 Real World

Scientists and engineers use line styles, markers, and colors to make graphs easier to read and interpret.

💼 Career

Knowing how to customize plots is important for data visualization tasks in research, engineering, and data analysis jobs.

1

Create the data vectors

Create a vector called x with values 1, 2, 3, 4, 5 and a vector called y with values 2, 4, 6, 8, 10.

MATLAB

% Create vectors x and y with the specified values
% Your code here

Need a hint?

Use square brackets to create vectors in MATLAB, separating values with commas.

2

Define the line style, marker, and color

Create a variable called style and set it to the string "--or" which means dashed line, circle markers, and red color.

MATLAB

x = [1, 2, 3, 4, 5];
y = [2, 4, 6, 8, 10];
% Define the style string
% Your code here

Need a hint?

The style string combines line style, marker, and color. '--' is dashed line, 'o' is circle marker, 'r' is red color.

3

Plot the data with the style

Use the plot function with variables x, y, and style to plot the data with the specified line style, marker, and color.

MATLAB

x = [1, 2, 3, 4, 5];
y = [2, 4, 6, 8, 10];
style = '--or';
% Plot the data using plot function
% Your code here

Need a hint?

Use plot(x, y, style) to apply the style string to the plot.

4

Display the plot with labels

Add title with text 'Dashed red line with circle markers', xlabel with 'X axis', and ylabel with 'Y axis' to label the plot.

MATLAB

x = [1, 2, 3, 4, 5];
y = [2, 4, 6, 8, 10];
style = '--or';
plot(x, y, style);
% Add title and axis labels
% Your code here

Need a hint?

Use title, xlabel, and ylabel functions to add labels.
