semilogx

Semilog plot (x-axis has log scale).

📝 Syntax

• semilogx(X, Y)

• semilogx(X, Y, LineSpec)

• semilogx(Y)

• semilogx(Y, LineSpec)

• semilogx(ax, ...)

• semilogx(..., propertyName, propertyValue)

• go = semilogx(...)

📥 Input argument

• X - Log scale coordinates: scalar, vector or matrix.

• Y - Linear scale coordinates: scalar, vector or matrix.

• LineSpec - Line style, marker, and/or color: character vector or scalar string.

• ax - a scalar graphics object value: parent container, specified as a axes.

• propertyName - a scalar string or row vector character. see help of 'line' for property list.

• propertyValue - a value.

📤 Output argument

• go - a graphics object: line type.

📄 Description

semilogx(X, Y) plots data using a base 10 logarithmic scale for the x-axis and a normal (linear) scale for the y-axis.

semilogx has the exact same syntax as the plot command.

💡 Examples

f = figure();
x = logspace(-1,2);
semilogx(x, x);
grid on

f = figure();
x = logspace(-1, 2, 15);
y = 13 + x;
semilogx(x, y, 'x', 'MarkerFaceColor', [0 0.447 0.741])
grid on
