Graph cursors
As shown in the following figure, the Cursor 
button (1) activates a cursor (2) on the Diameter chart that shows the current time position on the graph according to the images shown in the Video window. The coordinates (diameter value in millimeters and time value in the format minutes:seconds.milliseconds) of the cursor are dynamically updated and shown in (3). When the Cursor button is active, it is also possible to know the coordinates of an exact point in the graph; it is only needed to hover over the chart and a second cursor (4) is displayed. It follows the mouse movements and the exact coordinates of the point are shown in the label (5) (diameter value is expressed in millimeters and the time value has the format minutes:seconds.milliseconds).
