DataGrid 与chart联动Step By Step 2

还有一个头痛很久的鼠标触发问题，后来发现可以用<textarea cols="50" rows="15" name="code" class="c-sharp"> myChart.showDataTips = false; myChart.showDataTips = true;</textarea>

来实现无鼠标下显示datatip，同时showDataTips="true"

有一个Bug就是由于包含父容器，x，y坐标都不正确，原本打算用var pt:Point = localToGlobal (new Point(items[k].x,items[k].y));发现效果很差

我是在硬代码中微调的，可能留下隐患

var pt:Point = new Point(items[k].x+50,items[k].y+10);

这样就初步实现了联动
