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
