The GetChartPoint() method retrieves all the chart data for a single sample point. A sample point can have multiple measurements for it.

Syntax

'Declaration
 
Public Shared Function GetChartPoint( _
   ByVal characteristicId As Integer, _
   ByVal sampleId As Integer, _
   ByVal chartType As Integer _
) As DataSet
'Usage
 
Dim characteristicId As Integer
Dim sampleId As Integer
Dim chartType As Integer
Dim value As DataSet
 
value = Sample.GetChartPoint(characteristicId, sampleId, chartType)
public static DataSet GetChartPoint( 
   int characteristicId,
   int sampleId,
   int chartType
)

Parameters

characteristicId
Required. Holds the characteristic ID.
sampleId
Required. Holds the ID of the sample.
chartType

Required. An enumeration that indicates the chart type.

2 = Xbar + Range

3 = Xbar + Sigma

5 = IX + IR

7 = MA + Range

8 = MA + Sigma

16 = p

17 = np

18 = u

19 = c

20 = DPMO

Return Value

Returns a DataSet that contains the charting data for the sample and the characteristic.

The columns of the returned DataSet are described below.

Column Name

Description

sample_id

An integer that is the ID of the sample from which the characteristic measurement came. From the Sample table.

primary_cl

A double that is the center line for the primary graph in the chart. From the QM_Spec_Char_Link or Characteristic table.

primary_lcl

A double that is the lower control limit for the primary graph in the chart. From the QM_Spec_Char_Link or Characteristic table.

primary_ucl

A double that is the upper control limit for the primary graph in the chart. From the QM_Spec_Char_Link or Characteristic table.

secondary_cl

A double that is the center line for the secondary graph in the chart. From the QM_Spec_Char_Link or Characteristic table.

secondary_lcl

A double that is the lower control limit for the secondary graph in the chart. From the QM_Spec_Char_Link or Characteristic table.

secondary_ucl

A double that is the upper control limit for the secondary graph in the chart. From the QM_Spec_Char_Link or Characteristic table.

requested_time_local

A datetime that is the time when the sample was requested in the local time of the entity at which the sample was collected. From the Sample table.

request_time_utc

A datetime that is the time when the sample was requested in UTC. From the Sample table.

requested_time

A datetime that is the time when the sample was requested in the local time of the client application that is making the call. This value is calculated from the UTC date/time value and the call's time zone information.

note

A string that is the notes for the sample-characteristic pair. From the Sample_Char_Link table.

value_no

An integer that is the index of the measurement within the sample. From the Result table.

result_value

A double that is the value of the measurement. From the Result table.

act_sample_size

An integer that is the size of the sample if individual measurements are not being stored. From the Sample_Char_Link table.

Remarks

The center line and control limits returned from the point are obtained from the characteristic or from the overrides assigned to the QM specification assigned to the Sample/Characteristic pair. If a QM specification is assigned to the sample/characteristic pair and the QM specification has override values, those values are used; otherwise, the values assigned to the characteristic are used.
