Hi,

I have a simple PT100 sensor connected to my Logo 8.3, 

I have made a simple programme and also used the web editor to show the temperature of the sensor on a line graph that updates with time.

I can then use my phone or laptop to view the temperature graph on the local website.

My only issue is that I'd like to open the website for it to show the history of the sensor from an hour before, instead when I open the website the graph starts recording from when I open it.

Is there any way I can show the history of a sensor using the graph 

Many Thanks

Depending on the number of individual storages and program storage of the logo, you may be able to use a bucket chain storage

Here is an example for a bucked chains storage as Ella_68 has mentioned. Each value of the chain can be used in the web browser as little bargraph to show e.g. a trend for the last 4 or more hours. Just expand the chain for an amount as needed, if there is enough space for the program.
