For temporary purposes, just type "1 month" or "31 days" into the trend display's scope field.

If you want a trend to open up with a one month scope as default you need to create a new or edit the trend template. For new templates, you must also reconnect the trend aspect to use the new template (this is done on the trend's Config View).

Its recommended to create new & custom trend templates rather than adjusting standard ones (since customizations on standard objects/aspects may go lost if system is upgraded, etc.)

Additionally, any trend data request is capped at 86400 values (1 day of 1 second data).

For large time scopes we recommend using the "TimeAverage" treatment which will ask for interpolated values matching the trend X-axis resolution (aka Resample Interval). A one month scope may cause the resample interval to become 30 minutes.

Some libraries and/or customers desires non-interpolated trend data - for this we recommend the "ExtMomentary" treatment.

For historic reasons there also exists an older version called "Momentary" which we discourage from using since it does not perform any compression on the values between the log and the trend. You can say that ExtMomentary performs "WinZIP" on the values between the log and the trend and that saves memory & resources and hence gives better performance.

Without compression, the 86400 maximum number of values in each request may not allow to paint a complete month long trend. Hence, go for "ExtMomentary".

Treatment can be defined on the trend template as well.
