Bar graph.

📝 Syntax

• bar(Y)

• bar(X, Y)

• bar(..., width)

• bar(..., color)

• bar(..., propertyName, propertyValue)

• bar(ax, ...)

• b = bar(...)

📥 Input argument

• X - x-coordinates: scalar, vector or string array.

• Y - y-coordinates: vector.

• width - scalar, 0.8 (default).

• color - a scalar string or row vector character: color name or short color name.

• propertyName - a scalar string or row vector character.

• propertyValue - a value.

• ax - Axes object.

📤 Output argument

• b - patch graphics object.

📄 Description

bar(X, Y) creates a bar graph using two sets of X-Y data vectors.

When only one argument is provided (Y), it is interpreted as a vector containing Y values, and the X coordinates are generated as a sequence from 1 to the number of elements in the Y vector.

You can optionally specify the width of the bars.

A value of 1.0 will make each bar exactly touch its neighboring bars, while the default width is set to 0.8.

💡 Examples

f = figure();
y = [ 91 75 123.5 105 150 131 203 179 249 226 281.5];
bar(y);

f = figure();
y = [ 91 75 123.5 105 150 131 203 179 249 226 281.5];
bar(y, 0.5);

f = figure();
x = 1900:10:2000;
y = [75 91 105 123.5 131 150 179 203 226 249 281.5];
bar(x, y, 'r');

f = figure();
x = [ "Summer", "Spring", "Winter", "Autumn"];
y = [ 2 1 4 3];
bar(x, y);

f = figure();
y = [91 75 123.5 105 150 131 203 179 249 226 281.5];
bar(y, 'FaceColor', [0 .5 .5], 'EdgeColor', [0 .9 .9], 'LineWidth', 1.5)
