maloglog - Create loglog plot of microarray data

Syntax

maloglog(X, Y, 'PropertyName', PropertyValue...)

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

Arguments

Description

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

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

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

maloglog(..., '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);
