Java 在android中绘制图形？

我想画一张和下图一样的图。谁能建议我怎么画这张图吗。我已经使用开放图表时间图形库，但我不能绘制这种类型的图形。 比如：http://stackoverflow.com/questions/424752/any-good-graphing-packages-for-android/1856369

这可能会对您有所帮助。我如何在时间openchart图形中绘制日期线。我如何绘制12月15日等日期线？阅读那里的文档并发挥创意，这不是我们程序员应该做的，所有问题都没有简单明了的解决方案谢谢您的支持，但我在图形中创建日期线时遇到了一些问题。如图所示，或者我应该使用画布绘制此图？我认为这在画布上是可能的，一旦你使用onmeasure确定X，Y的最大值，你就可以确定Y轴所需的比例，得到你的最大值，即85厘米减去65厘米，例如，在Y轴比例间隔的范围内，你可以算出比率，可以使用moveTO绘制xy线，这需要很多耐心和计划，因为你还需要绘制日期的垂直线。
