💡 Hint

Common Mistakes

Using x twice instead of y for the second argument.

Passing a range instead of the y vector.

The scatter function plots points using x and y coordinates. Here, y is the vertical data.

💡 Hint

Common Mistakes

Using color names without quotes.

Using an unsupported color string.

The fourth argument in scatter sets the color of the points. 'red' colors points red.

Fix the error in the code to plot a scatter with circle markers.

MATLAB

x = 1:4;
y = [5, 10, 15, 20];
scatter(x, y, 100, 'b', [1]);

💡 Hint

Common Mistakes

Using '*' which is star marker, not circle.

Omitting quotes around the marker.

The marker type 'o' specifies circle markers in scatter plots.

Fill both blanks to create a scatter plot with blue square markers and size 50.

MATLAB

x = 1:3;
y = [7, 14, 21];
scatter(x, y, [1], [2], 's');

💡 Hint

Common Mistakes

Swapping size and color arguments.

Using wrong marker type.

The third argument sets marker size (50), the fourth sets color ('blue'), and 's' sets square markers.

Fill all three blanks to create a scatter plot with green diamond markers, size 75, and label the x-axis as 'Time'.

MATLAB

x = 1:4;
y = [10, 20, 30, 40];
scatter(x, y, [1], [2], '[3]');
xlabel('Time');

💡 Hint

Common Mistakes

Using wrong marker character.

Forgetting quotes around color or marker.

Size is 75, color is 'green', and 'd' sets diamond markers. xlabel labels the x-axis.
