TiPlotChannelCustom.Count
TiPlotChannelCustom See Also
Used to get the number of data points already added to the channel or to set
the channel data buffer size capacity.
property Count : Integer;
Description
Use Count to get the number of data points already added to the channel or to
set the channel data buffer size capacity. If you set the count to a lower
number, the buffer size will be reduced and any data truncated will be lost. If you
do not want the buffer to be resizing while data is being added, set the count
to the maximum number of data points that you expect to be added. The buffer
capacity will increase its size by 25% when a data point addition exceeds the
current capacity.
Instead of using the Count property to manage the data buffer size, set the RingBufferSize to a non-zero value to limit the buffer to a fixed size.
Example
Delphi
Value := iComponent.Channel[0].Count;
C++ Builder
Value = iComponent->Channel[0]->Count;
