I'd like to have a graph where I show my data (production rate for example) in the vertical axis(y ), and in the horizontal axis (x) the create_date.

I declared this last one in my object attributes, so I can use it, when I tried to get it from the DB in the [module_view.xml] file it does show up in the graph and I get a direct line (horizontal line) instead of a graph.

I tried with another field of mine 'date' of type datetime, and give it the default value of the current system date (datetime.today() ), but it didn't work either.

Is something wrong with what I did ? How can I do this ?

Later I'd like to show this data in realtime, how is this possible ?
