Mahboob - 2 steps forward, but 1 step backward to where we were a few weeks ago.  Lines are being plotted (in the form of points which is OK) connecting the individual valuation data points. So when say a High Valuation drops, there is a vertical line to the lower value - there should be no vertical lines. The data points are independent of one another - what we need is more like a scattergram. (And filling in the months where there are no values to the previous month's values.)
