TOPIC: History DB Trend

I use remote Mysql to store data and history db trend to show data. It's ok in my computer, but there aren't any history trend lines in my Android phone. Why?
Thank you!

Did you check your MySQL database? Does any history data saved there? Did you check date period when you use History DB Trend on your computer?

Best regards,

In my computer there are some trend lines between January 27th and February 1st. but there are no trend line in my android phone

Did you try to use shorter period?

Sometimes, we need history trend, and history data can be generated by our program. All people can see the same history trend line. Is there any way to achieve it?
The test project is attached.
