SuitLines.java 的 calcUnitXY()方法
float scale = new BigDecimal("1").subtract( (new BigDecimal(Float.toString(curValue)) .subtract(new BigDecimal(Float.toString(minAndMaxOfY[0])))) .divide(new BigDecimal(Float.toString(absValueOfY)), 2,BigDecimal.ROUND_DOWN)
在最大数据等于400
当前值为 250 和 249时
1-250/400 =0.375
1-249/400 =0.3775
如果只保留小数到2位 则画出来的高度是一样的 建议多保留几位小数。
