Candle Chart Axis.java has one line missing in a constructor

[krishnak]

Discussed in #120

The CandleChartTest when executed throws a null pointer error as axisBounds is NOT initialised in the constructor which takes a date time.

Fix: Add a line before line 313 in Axis.java

        axisBounds                        = new Bounds();

Work around for others who don't want to wait for the new maven release.

Copy the Helper.java to your project and replace line 1315 to

         Axis axis = new Axis(START.toEpochSecond(getZoneOffset()),END.toEpochSecond(getZoneOffset()), Orientation.HORIZONTAL, AxisType.LINEAR,Position.BOTTOM, "Time");

Make sure you use this version of helper and not the one from the library
