Used for getting a specific piece of data from a specific channel and returns
a boolean indicating if the data is null.
function GetChannelDataIsNull(Channel, Index: Integer; var Data : Double) : Boolean;
Description
Use GetChannelDataIsNull to get a specific piece of data from a specific
channel and returns a boolean indicating if the data is null. When time indexes are
added to the strip chart, each channel tracks the highest data point set for
that channel using the ChannelData property or the SetChannelsData method. All
data points after the highest data point are considered null.
Example
Delphi
DataIsNull := iComponent.GetChannelDataIsNull(0, 20, Value);
C++ Builder
DataIsNull = iComponent->GetChannelDataIsNull(0, 20, Value);
Note: Channel and Index are zero based.
