CimData, the interface for both the X and Y series vectors, has a property called Item.
Item:
Allows you to get and set
individual data values within the vector.
Is the default property of
CimData. It can be invoked without having to write its name.
Returns a single variant type when retrieving data and
expects a single variant
type when setting the data.
This variant type can be a single value of any of the following Basic types that result in a numeric value including:
Integer
Long
Single
Double
Decimal
Boolean
Byte
Variant
String
To invoke the Item property to retrieve data you can use either of the following two formats:
X = CimData.Item(n)
X = CimData(n)
Where
n is the location of the data value you are retrieving.
To invoke the Item property to set data you can use either of the following two formats:
CimData.Item(n) = X
CimData(n) = X
Where
n is the location of the data value you are setting.
Scripting examples for setting single and array values include:
Example 1. Access Data Values from a Series Vectors
Series name: Series 1
Script purpose: Set a point to the third Y data value
Procedure:
Open the CimEdit Properties dialog box for the XY Plot control object.
Display the Edit Script tab.
' Define the point:
Dim x As New Point
x.Id ="X_POINT"
' Set the point to the third Y data value in the series:
x.SetValue = cimOleObj.Series("Series 1").Data.Y(2)
Example 2. Set Individual Data Values to a Particular Value
Series name: Series 1
Script purpose: Set the fifth X data value to the value of a point
Procedure:
Open the CimEdit Properties dialog box for the XY Plot control object.
Display the Edit Script tab.
Write the following Basic excerpt within a subroutine.
' Define the point:
Dim x As New Point
x.Id ="X_POINT"
' Set the fifth X (which has an index of 4)
' data value in the series:
cimOleObj.Series("Series 1").Data.X(4) = x.GetValue
Example 3. Set Individual Data Values to Unavailable
Series name: Series 1
Script purpose: Set the fourth y data value to null, the fourth X data value to empty
Both operations result in the value being unavailable.
Procedure:
Open the CimEdit Properties dialog box for the XY Plot control object.
Display the Edit Script tab.
Write the following Basic excerpt within a subroutine.
' Set the fourth X and Y data values to unavailable
' (either null or empty):
cimOleObj.Series("Series 1").Data.Y(3) = Null
cimOleObj.Series("Series 1").Data.X(3) = Empty
