Excel 2010图表 - 可以在图表点周围绘制椭圆吗？

I have no idea how to approach this problem so any pointers are appreciated. We have Lat & Long points charted in Excel 2010 in a standard X-Y plot. For each data point coordinate we have additional data defining an ellipse of error associated with that data point (major axis, minor axis, and angle). The ellipse represents a search area. Is it feasible to draw the ellipse around each data point? We have all the data and can chart the x-y points OK, but clueless on how to draw the ellipses in Excel/VBA or if it's even possible. Many thanks. Have searched without success.I have no idea how to approach this problem so
