i won't comment on what data should be available as charts to the
user, but i can comment about the realization of the charts in terms
of software.

attached is a demo project that uses the Chart.js library v2.*:
https://github.com/nnnick/Chart.js/

the idea here is that QML / JS can be used to create interactive (and
supposedly portable) charts.

you can unzip the archive and start it with:
$qml main.qml
(given you have the "qml" binary from the Qt package in PATH).

this is WebView based, but the library also has QML bindings here,
which seem outdated:
https://github.com/jwintz/qchart.js/tree/master

i haven't tested this idea on mobile, but if it works, it makes a
point that QML / JS can be used to display charts to the user in a
portable manner for both the desktop and mobile apps.
