table to timetable conversion problems
显示 更早的评论
the problem arises after the conversion (T=table2timetable(TICKTYPE); . I attach the sparkline of the "TICKTYPE" table preview and the succesive sparkline "T" in the timetable. the "x_BID_" column has strange horizontal lines that change the values of subsequent data processing like tt= retime(T,'regular','mean','TimeStep',seconds(10)); here the mean values are completely different from the values of "T" file.tks very much. I also attach the T file in .mat

You have only shared a subset of your data, so we are not able to reproduce the issue. However, I suspect what has happened is your timetable is creaed using time of day, and your full dataset is from multiple days. The timetable uses the time information to create the sparkline, but since your rowtimes do not include date, the data from multiple days now overlap based on time only. I suggest creating a datetime column by combining time and date, and use that as your rowtimes.
Perhaps something like this:
TICKTYPE.DT = datetime(TICKTYPE.x_DATE_,'InputFormat','yyyy.MM.dd')+TICKTYPE.x_TIME_
T = table2timetable(TICKTYPE,"RowTimes","DT")
