What is this chart trying to say? There are no axis labels, no tick marks and no vertical axis at all. The vertical scale is far too wide to see the slight variations. There is a faint band across the chart that is hard to see. What does that mean? (At first I thought the band might be one or two SD from the mean, but it is neither, since most of the time, all the markers lie below the band. It seems like it should relate to the label below the chart but it doesn't.) I assume the x axis is the day of the month but even that is unclear. How can I scroll to see earlier periods? How to change the date range?
How can a major supplier like Samsung produce such ***?
