Syntax

addTitle(hm_cg_object,title)
addTitle(hm_cg_object,title,Name,Value)
textObj = addTitle(___)

Description

addTitle(hm_cg_object,title) adds a title to the heatmap or clustergram.

example

addTitle(hm_cg_object,title,Name,Value) specifies the title text object properties using name-value pair arguments. For example, addTitle(hm_cg_object,'Gene Expression Data','Color','red','FontSize',12) displays the title in red 12-point font. You can specify multiple name-value pairs. Enclose each property name in quotes.

example

textObj = addTitle(___) returns a text object textObj used as the title of the heatmap or clustergram using any of the input argument combinations in the previous syntaxes.
