Problem with chart

[Zee]

I want to display last week and month in two separate charts. Problem is that I can not change time and date so it will display correctly.

Graph named "siste uke" is last week and "siste måned" is last month

If I understand you correctly, when you set the offset of each chart, also set the XScale.Maximum. Take the current time and add number of seconds in a week to one, number of seconds in a month to the other.

I tried that, but it didn't work. Maybe i misunderstood what to do.
I tried something else, copy/paste from one VI that was correct.

Now I have a new problem.

I have a main VI (Hovedprogram) and 5 VI's (Ferdigprogram temp tur , Ferdigprogram temp retur, Ferdigprogram nivå, Ferdigprogram temp i fyr and Ferdigprogram trykk)who starts when I start the main VI.

I want to display data for last 15 seconds, last 24 hours, last week, last month and last year.
The problem is that the graphs for last week, last month and last year do not display all the data's. I just got a dot where I started the program 28.April. The graphs shows the data's from 2.May
Any suggestion how I can change my program to appear as described?

And here is one of the 5 VI's

And the sub VI for sending the (alarm)message to e-mail
