这两天的成果……
终于拿 WPF 完成了图表控件,这两天早上一直在折腾这个。
似乎现成的 WPF 图表控件有不少,不过 License 都不符合要求,而且太复杂了,最后还是决定自己写个吧。
本想用上自定义控件,再用 XAML 自动绑定数据,支持皮肤等等等等,做个独立的图表控件……最终还是放弃了,现在还玩不转 。
感谢 lyanry 的殷切指导,最终的效果还不错~
支持自定义范围、放大、数据点热点,就是大量数据时绘图有点慢。

@Yue Wang: 代码很简单,因为为了实现数据热点之类的,就没有用底层库画图,直接在一个 Canvas 上面放椭圆控件,最后连起来,坐标轴的文字也都是 Label 控件。
目前正在实现打印功能,这次就只能自己画图了,痛苦中……
同步数据?更新数据数组,然后刷新图像就搞定了,是这个意思吧 :)

Online hrt therapy is an option for both new and existing patients. New patients considering hormone therapy can have all of their questions answered and make a determination as to whether they are an appropriate candidate for therapy. Existing patients who are already on a hrt therapy protocol can seamlessly migrate to an online hrt clinic without having to interrupt their current protocol. Existing hrt patients will still be required to complete a hormone blood test panel. Existing male patients will need to ensure that the blood test is taken 5 days after prior administration of a hormone therapy protocol. Existing female patients will be asked to take their blood test within days 12 to 23 of their respective hormone cycle. This will ensure that a proper level is measured as it relates to hormones. online hrt therapy
