[BasicUI] Show charts for all Items

Which UI are you reporting an issue for?

• HABot
• CometVisu

The problem

Some time ago I implemented the ability to show a chart for any Item on a Sitemap in the Android app: openhab/openhab-android#3636
The chart can be displayed by long-pressing on a widget and select "Analyse" in the popup menu.

Due to this feature my Sitemap doesn't contain any chart explicitly anymore as I can show a chart anytime for any Item. It makes creating Sitemaps faster and they aren't disrupted by charts when I don't need them.
I'd like to have the same feature in Basic UI.

Your suggestion

I'm not sure about the UI/UX in Basic UI for this feature. Maybe override the right-click menu and add a button "Analyse" there?

Not sufficient, it would not be accessible on a smartphone or tablet.

The same menu could be opened when long-pressed on a device with touch input.
