Method Detail

getTickUnits

java.lang.String[] getTickUnits(double minValue,
                                double maxValue,
                                int maxCount,
                                boolean includeZero)

根据最小值和最大值及数据的最大个数来确定坐标轴上的刻度值.

Parameters:

minValue - double 最小值.

maxValue - double 最大值.

maxCount - int 刻度值的最大个数,必须大于0.

includeZero - boolean 布尔值,是否包含0值.

Returns:

String[] 刻度值非空数组,且值按由小到大的顺序排列,数组的每个元素都是数字,(不为null).
