The package com.objectplanet.chart102 includes charts for JDK 1.0.2
ChartSample: the method formatNumber(double value, int decimals) was added for formatting floating point numbers (used instead of the NumberFormat class only found in JDK 1.1)
Numbers are now formatted with three and three digits with space between them (European style) instead of commas (American style).
Chart: Fixed a bug in the getFloatMaxValue() and getFloatMinValue() that caused them to return Long.MIN_VALUE and Long.MAX_VALUE if no samples were present, they now return 0 if no samples are found.
LineChart: Same fix as above.
LineChart: fixed a bug in the setSampleColors(Color[] colors) that always caused the third color be overwritten.

Changes from version 1.3.3 to 1.4
