You mean that right now when you open up the trend you can't see any previous data?
A trend itself doesn't store any data so if you open up a trend it will start to display new incomming data which will be lost when you close it and open it again.
To get the trend to keep and be able to show previous data you would need to set up a "log configuration" to store the data so the trend can display previous values from the log.
