Question

Answer 1

There's a post about that topic in the documentation:

http://www.android-graphview.org/documentation/label-formatter

There is also a specific example for dates in axis - "Use Dates as Labels".

If you set the X value as Date object or as unix epoch (millis from 1970-01-01) then you can easily use this predefined label formatter:

graph.getGridLabelRenderer().setLabelFormatter(new DateAsXAxisLabelFormatter(getActivity()));

Answer 2

You can use a custom list of horizontal labels, like this:

barGraphView.setHorizontalLabels(new String[]{"1/1/1970", "1/2/1970", "1/3/1970"});

I did something similar by constructing the String array using a for-loop.
