Plots of an sqlite database using canvas  This app is based on an app on my Linux system  which is written in Qt4/Python.   The x axis is always time and can be altered via preferences. Any reasonble time frame (3 years or more) requires lots of horizontal   space so a tablet would display it better than a mobile.  There are five plots, selectable via buttons and some of them allow  zooming in for more detail. There is also swipe support in the 'distance'  and 'time' plots.
