loglog

Log-log scale plot.

Syntax

• loglog(X, Y)
• loglog(X, Y, LineSpec)
• loglog(Y)
• loglog(Y, LineSpec)
• loglog(ax, ...)
• loglog(..., propertyName, propertyValue)
• go = loglog(...)

Input argument

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

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

loglog has the exact same syntax as the plot command.

Examples

f = figure();
x = logspace(-1,2);
y = 2 .^ x;
loglog(x,y)
grid on

f = figure();
x = logspace(-1,2,20);
y = 10 .^ x;
loglog(x,y,'s','MarkerFaceColor',[0 0.447 0.741])
grid on
