DataPointLabels

Scope	Pesgo, Pe3do, Pepso
Type	Property Array of type String
Default	empty
.NET	PeString.DataPointLabels
Ocx\|Vcl	DataPointLabels
DLL	DataPointLabels

Purpose

This property identifies data labels which will be placed next to data points when AllowDataLabels equals PEADP_DATAPOINTLABELS and GraphDataLabels equals TRUE. Each string in the tab delimited array should be less than or equal to 48 characters in length.

Comments

PeString.DataPointLabels members of Pesgo.PeString, Pe3do.PeString, Pepso.PeString

This property is similar to YData in that it assigns a piece of data to each data-point. Thus, if you pass 100 data-points to YData, you will also pass 100 strings to this property.

When used with PEvget, the destination buffer must be large enough to hold all of the tab delimited string information. For property arrays, calling PEvget with lpDest equal to NULL will return the number of bytes needed to hold the data.

The format of the data is defined by the SubsetByPoint property.

WinForm VB.NET Example

PEGraph1.PeString.DataPointLabels(0, 0) = "Texas"

PEGraph1.PeString.DataPointLabels(0, 1) = "California"

PEGraph1.PeString.DataPointLabels(0, 2) = "Florida"

PEGraph1.PeString.DataPointLabels(0, 3) = "Washington"

OCX Example

PEGraph1.DataPointLabels(0, 0) = "Texas"

PEGraph1.DataPointLabels(0, 1) = "California"

PEGraph1.DataPointLabels(0, 2) = "Florida"

PEGraph1.DataPointLabels(0, 3) = "Washington"

VCL Example

PEGraph1.DataPointLabels[0, 0] := 'Texas';

PEGraph1.DataPointLabels[0, 1] := 'California';

PEGraph1.DataPointLabels[0, 2] := 'Florida';

PEGraph1.DataPointLabels[0, 3] := 'Washington';

C / C++ Example

/* set 4 tab delimited data point labels */

char szDataPointLabels[] = "Texas\tCalifornia\tFlorida\tWashington\t";

PEvset (hWndPE, PEP_szaDATAPOINTLABELS, szDataPointlabels, 4);
