DataRange::SetTree

SetTree

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. 
{
    Worksheet wks = Project.ActiveLayer();
    if( wks )
    {
 
        Tree trXYSelection;
        DWORD dwRules = DRR_GET_DEPENDENT | DRR_NO_FACTORS;
        init_input_data_branch_from_selection(trXYSelection, dwRules);
        out_tree(trXYSelection);
 
 
        DataRange dr,drSub;
        string strRange;
        dr.Create();
        dr.SetTree(trXYSelection, bOneData);
 
        DWORD dwPlotID; // This is to retrieve DataPlot UID if present
        vector vX, vY;
        double xmin, xmax, ymin, ymax;
        int nNumDatasets = dr.GetNumData(dwRules);
        for( int nIndex = 0; nIndex < nNumDatasets; nIndex++ )
        {
            // Copy data associated with nIndex of dr into vectors using DataRange::GetData
            dr.GetData(dwRules, nIndex, &dwPlotID, NULL, &vY, &vX);
 
            // Now we have made a copy of XY data into vectors vX and vY
            // so we can do analysis on the data...for example:
            vX.GetMinMax(xmin, xmax);
            vY.GetMinMax(ymin, ymax);
            dr.GetSubRange(drSub, dwRules, nIndex);
            strRange = drSub.GetDescription();
            printf("%s\nxmin = %g\nxmax = %g\nymin = %g\nymax = %g\n", strRange, xmin, xmax, ymin, ymax);
        }
    }
}
