假设有4条曲线，通过脚本(画面的OnOpenPicture事件中)来实现各自所连接的归档变量：
char* lpszTrendName="Trend";//曲线控件名
SetPropWord(lpszPictureName,lpszTrendName,"Index",3);
SetPropChar(lpszPictureName,lpszTrendName,"TagName","ArchiveName1\\TagName4");
SetPropWord(lpszPictureName,lpszTrendName,"Index",2);
SetPropChar(lpszPictureName,lpszTrendName,"TagName","ArchiveName1\\TagName3");
SetPropWord(lpszPictureName,lpszTrendName,"Index",1);
SetPropChar(lpszPictureName,lpszTrendName,"TagName","ArchiveName1\\TagName2");
SetPropWord(lpszPictureName,lpszTrendName,"Index",0);
SetPropChar(lpszPictureName,lpszTrendName,"TagName","ArchiveName1\\TagName1");
TlgTrendWindowPressStartStopButton("TrendCaption");//激活[开始]按钮
TlgTrendWindowPressLinealButton("TrendCaption");//激活[标尺]按钮
