android – Achartengine线图

概述我正在使用Achartengine来创建折线图.我现在的月份显示,但上个月的第二行没有显示出来.这是lass和logcat：所以从logcat可以看出我的日期是正确的,上个月的计数也是正确的.那么为什么它没有显示超出我.

哦,这是那些颜色：

<color name ="base">#51bbc2</color>    <color name ="complementary">#C25951</color>

解决方法 谢谢@Dan你带我到解决方案.我去了并记录了所有的点,以确保所有正确的值都放在正确的数组中,然后找出yArray.add(c.getInt(c.getColumnIndex(StatusData.KEY_CHARTING_TEMPERATURE)));不知何故被删除了.所以现在它有效！好极了！ 总结
