This is a major release, with a few breaking changes. So please pay attention.

Updates:

• The Integer x-index is dead. Intoducing: x-values (float). Each entry now has an x and a y.
• Pie/radar charts do not have a concept of X index anymore
• Unified XAxis/YAxis features and experience.
• Unified formatter interfaces for axes.
• Major refactoring of the Highlight mechanism.
• Refactored marker mechanism
• Refactored legend entry mechanism
• Each dataset can now set its own legend form/size/etc.
• More demos
• Many minor bug fixes and improvements

Breaking changes / how to migrate:

• All dataset constructors have changed - they do not take an array of x-indices anymore.
• All entry constructors have changed - they take in an X and a Y.
• Pie and Radar chart entries now have their own classes. So exchange the Entry classes withPieEntry/RadarEntry
• If you have any old startAtZeroEnabled calls - these have been deprecated for a long time. Replace them with axisMinimum.
• In general, all functions that accepted x-indices before, now accept an x-value, so you might have to adjust the names a little bit.
• Where OnChartValueSelectedListener is implemented, update the onValueSelected interface
• Replace drawSliceTextEnabled with drawEntryLabelsEnabled
• If you have a custom scatter shape - implement an IShapeRenderer, and put your rendering code in there
• If you have a custom marker - consider subclassing MarkerView/MarkerImage or implementing IMarker. There are more options than before now...
• If you have used barSpace before, move to using barWidth
