maloglog

Create loglog plot of microarray data

Syntax

maloglog(X, Y)
maloglog(X, Y, ...'FactorLines', N, ...)
maloglog(X, Y, ...'Title', TitleValue, ...)
maloglog(X, Y, ...'Labels', LabelsValues, ...)
maloglog(X, Y, ...'HandleGraphicsName', HGValue, ...)
H = maloglog(...)


Arguments

X, Y	DataMatrix object or numeric array of microarray expression values from a single experimental condition.
N	Property to add two lines to the plot showing a factor of N change.
TitleValue	A character vector or string to use as the title for the plot.
LabelsValue	A cell array of character vectors or string vector containing labels for the data in X and Y. If you specify LabelsValue, then clicking a data point in the plot shows the label corresponding to that point.

Description

maloglog(X, Y) creates a loglog scatter plot of X versus Y. X and Y are DataMatrix objects or numeric arrays of microarray expression values from two different experimental conditions.

maloglog(X, Y, ...'PropertyName', PropertyValue, ...) calls maloglog with optional properties that use property name/property value pairs. You can specify one or more properties in any order. Each PropertyName must be enclosed in single quotation marks and is case insensitive. These property name/property value pairs are as follows:

maloglog(X, Y, ...'FactorLines', N, ...) adds two lines to the plot showing a factor of N change.

maloglog(X, Y, ...'Title', TitleValue, ...) allows you to specify a title for the plot.

maloglog(X, Y, ...'Labels', LabelsValues, ...) allows you to specify a cell array of character vectors or string vector containing labels for the data. If LabelsValues is defined, then clicking a data point in the plot shows the label corresponding to that point.

maloglog(X, Y, ...'HandleGraphicsName', HGValue, ...) allows you to pass optional Handle Graphics^® property name/property value pairs to the function.

H = maloglog(...) returns the handle to the plot.

Examples

maStruct = gprread('mouse_a1wt.gpr');
Red = magetfield(maStruct,'F635 Median');
Green = magetfield(maStruct,'F532 Median');
maloglog(Red,Green,'title','Red vs Green');
% Add factorlines and labels
figure
maloglog(Red,Green,'title','Red vs Green',...
                'FactorLines',2,'LABELS',maStruct.Names);
% Now create a normalized plot 
figure
maloglog(manorm(Red),manorm(Green),'title',...
                'Normalized Red vs Green','FactorLines',2,...
                'LABELS',maStruct.Names);
