Line chart pop-up menu not documented

[ajdapretnar]

I added a short note in the documentation. However, these are standard pyqtgraph options, so please refer to their own documentation.

Well, I as a user don’t necessarily know, or for that matter care, what particular graphics library is being used, so that I can go search for what happens to be the standard behaviour of that package :-p
I had at look at https://orangedatamining.com/widget-catalog/time-series/line_chart/, but I guess the note in the documentation hasn’t found it’s way to the web page yet.

Still, I think the min/max values of the x axis are a bit cumbersome to use, if they actually are given as seconds.

I see no non-intrusive way to inform the user about right-clicking. (Nobody particularly likes the popup hints that appear in some widgets, so we avoid them). Perhaps we could add a button that would open the same pop-up as one gets by right-clicking?

As for time in seconds: this is handled by pyqygraph. Pyqtgraph is by far the best option for plotting data in our context (we know, we used quite a few), but it can make breaking changes from version to version. I think I know how we could perhaps force it to maybe accept a different input (including parsing dates), but I'm pretty sure this would break in one of the future versions. We should probably add a different way to set the time range.

Oh, I don’t require an interactive help for the context menu—I’m perfectly happy with the options being described on the documentation web page. I’d even be happy with just a link to the relevant pyqtgraph documentation, as long as I don’t have to read the source code to figure out how things work :-)

Very annoying with non-backwards-compatible updates, I feel for you.
