The CHART record marks the start of the chart data substream in the workbook BIFF stream. This record defines the location of the chart on the display and its overall size. The x and y fields define the position of the upper-left corner of the bounding rectangle that encompasses the chart. The position of the chart is referenced to the page.
The dx and dy fields define the overall size (the bounding rectangle) of the chart, including title, pointing arrows, axis labels, etc.
The position and size are specified in points (1/72 inch), using a fixed-point format (two bytes integer, two bytes fraction).
