Description

Specify a datarange from a tree

Syntax

BOOL SetTree( TreeNode & tr, int nOption = DRTREE_DEFAULT )

Parameters

tr: [input]the TreeNode containing the range data
nOption: [input]one of the values from the enumeration:; enum {; DRTREE_DEFAULT = 0, // multiple ranges are added such that node name is used for the corresponding range name; DRTREE_ONE_DATA, // like DRTREE_DEFAULT, except that only one data node is considered; DRTREE_ANOVA_ONE_WAY_RAW, // the tree node passed is appropriate for one-way ANOVA data in raw form; DRTREE_ANOVA_ONE_WAY_INDEXED, // the tree node passed is appropriate for one-way ANOVA data in indexed form; DRTREE_ANOVA_TWO_WAY_RAW, // the tree node passed is appropriate for two-way ANOVA data in raw form; DRTREE_ANOVA_TWO_WAY_INDEXED, // the tree node passed is appropriate for two-way ANOVA data in indexed form; };

Return

TRUE if successful.

Examples

EX1

//This example need active one or multiple selected xy subranges. Will
//print out the minimum and maximum X and Y values of active worksheet.
void DataRange_Create_Ex2(BOOL bOneData = FALSE)//TRUE means only one range is added to tree. FALSE means add multiple ranges.
