andre_pulse Posts: 30 Rating: (4)	Hello How to clear trend data in FunctionTrendControl? Did not find the information on this issue. In subjects about wincc encouraged to use "DeleteData" property, but this method does not work in TIA and there is no description in the documentation. Please, can you help me to solve this problem Thank you

andre_pulse Posts: 30 Rating: (4)	So, now, I am using Visible property of trend (Off and then On) like: SetPropBOOL("Screen_name","function_trend view_1","TrendVisible",FALSE); SetPropBOOL("Screen_name","function_trend view_1","TrendVisible",TRUE); But this method not useful, because end point of old trend (which we clean) is first point of new trend. How to use "DeleteData" properrty? Thanks
