内存超出，同时使用实时多线。 [英] Memory exceeds, while using real time multi line.

问题描述

内存超出，同时在WPF中使用实时多行（40行）图表。 



我正在尝试为多线图建模在Wpf中使用chartingToolkit库。图表/图表必须运行至少8-10小时。存在线性进程内存增加的问题（高达800 MB或更多）。我需要从串行Com端口绘制实时数据（不同的
从站）。我从DispatcherTimer调用2进程UpadateValue和UpdateChart。
$




运行此程序时，进程内存随时间线性增加（超过900Mb）从任务经理观察.. !!）。

请给我一些解决记忆问题的事情。



非常感谢


我尝试过：

Memory exceeds, while using real time multi line (40 lines) charts in WPF. 

I am trying to model a multi line chart using chartingToolkit library in Wpf. The graph/chart has to run for atleast 8 -10 hrs. There is problem of linear process memory Increase (upto 800 MB or more). I need to plot real time data from serial Com Port (different slaves). I am calling 2 process UpadateValue and UpdateChart from DispatcherTimer.


While running this program, Process memory increases linearly with time (more than 900Mb observed from Task Manager..!!).

Please suggest me some things to resolve memory issue.

Thanks a Lot
