Active DataSet in Trend

Hi,

I have a trend in my display, and this trend has 5 data sets that are out of scales.

So, in this in way, i would like, that everytime someone open this displays, the trends shows only 2 of those 5 datasets.

Everytime i open this display, all dataset becomes actives.

So, how can i keep only some datasets active in my trend.

Let me know, if it is not clear, and sorry my english.

Thanks Again.
