Dont show trend data in history period longer than 2d for colected items

[Rudorufu-san]

Describe the bug
In the case of choosing a collection of multiple data from multiple items, NoData will be displayed. A longer time is set to more than 2d, e.g. 30d. In the case of choosing only one item and a long period of 30 days, the graph will be displayed without any problem.

Expected behavior
The expected behavior is the display of graphs from multiple items in one view for a selected long period of 30 days or more.

Screenshots

same problem, but in my case it still shows 15d when I put it in "relative time" is there anything new to solve this?
