I would just like to have a top strip on every page I designed.
I created a web panel and set it to be an Header panel. I then exported the Web panels and I noticed that on the browser (Chrome / IE and Edge) I got no top strip.
Here is a screenshot of mervis IDE.

Thanks a lot for the answer.
I'll take a look at mervis db.
Local storage feature could be anyway very handy.

I can't figure out the right way to configure a graph with history.
Every time I refresh the webpage the graph restarts drawing from the current sample.
Is there a way to keep the data? I'd like to have at least 3 days of history.

I set webpanel to be the header. Unfortunately that panel is not working at all. It's not shown at all.
Should I do something else?
