斑竹已经讲的很清楚了。
如果一个趋势控件control1，有两条曲线。
按钮脚本写：
SetPropWord(lpszPictureName,"Control1","Index",0);
SetPropChar(lpszPictureName,"Control1","TagName","Power\\ACCT1");
SetPropWord(lpszPictureName,"Control1","Index",1);
SetPropChar(lpszPictureName,"Control1","TagName","Power\\ACTT2");

SetPropChar(lpszPictureName,"Control1","Command","Reload");

至于名字的问题，趋势控件有个属性按钮，本身就可以显示该曲线的变量标签和数值的。
