TiPlotChannelCustom.MaxDataPoints
TiPlotChannelCustom
Retrieves the theoretical maximum number of data points that can be added to
the channel.
property MaxDataPoints : Integer;
Description
Use MaxDataPoints to retrieve the theoretical maximum number of data points
that can be added to the channel.
Warning!: this property is a simple theoretical maximum and assumes that your
application and other channels are using no memory in your application. The actual
maximum number of data points available to the channel will depend on the amount of
memory in use by your entire application (our component, other components,
application variables, etc) and by other channels in the Plot Component.
Note: The maximum amount of memory available to an application under 32-bit
Windows (Windows 95/98/ME/NT4/2000/XP) is 2GB, so this maximum is based on that
limit. When a 64-bit version of Windows and a 64-bit version of our Plot components
are released, this limit will be dramatically increased.
Memory Note: if you will be using large numbers of data points, you will need to
investigate the total memory usage needed by your application and adjust your virtual
memory settings in your operating system accordingly. Using the Compact data
styles instead of the Standard data style will greatly reduce the memory
requirements of your channel data set.
Example
Delphi
Value := iComponent.Channel[0].MaxDataPoints;
C++ Builder
Value = iComponent->Channel[0]->MaxDataPoints;
Note: This property is Read-Only
