2021-02-13	statistics: implement primitive "restrict to selection" feature	Berthold Stoeger
	Allow the user to restrict the analyzed dives based on the current selection. One button restricts to the current selection and one button resets the restriction. Thus, the user can for example select bars in the bar chart or a range in the scatter plot and perform statistics on these sets. The restriction works on top of the filter. The UI can certainly be improved, but it is a start. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-10	statistics: convert chart to QQuickItem	Berthold Stoeger
	It turns out that the wrong base class was used for the chart. QQuickWidget can only be used on desktop, not in a mobile UI. Therefore, turn this into a QQuickItem and move the container QQuickWidget into desktop-only code. Currently, this code is insane: The chart is rendered onto a QGraphicsScene (as it was before), which is then rendered into a QImage, which is transformed into a QSGTexture, which is then projected onto the device. This is performed on every mouse move event, since these events in general change the position of the info-box. The plan is to slowly convert elements such as the info-box into QQuickItems. Browsing the QtQuick documentation, this will not be much fun. Also note that the rendering currently tears, flickers and has antialiasing artifacts, most likely owing to integer (QImage) to floating point (QGraphicsScene, QQuickItem) conversion problems. The data flow is QGraphicsScene (float) -> QImage (int) -> QQuickItem (float). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2021-01-03	statistics: implement a statistics widget on desktop	Berthold Stoeger
	Implement a widget that shows the statistics state as comboboxes and the statistics chart. Calls into the statistics code if any of the comboboxes changes. The hardest part here is the formatting of the charts list with its icons and with headings. Sadly, it is not trivial to arrange icons horizontally. Therefore we would have to fully reimplement the ComboBox view, which is probably not fun. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
