marks a cross on it if you click.

You can trace a rectangular zone on the graph using the cursor, to zoom and display details.
The graph has two vertical lines (CURSOR A and CURSOR B). The time and value of the data item is
displayed above and to the right of each cursor.
If you move the mouse cursor to cursor A or cursor B, you can drag the latter left or right. There is a slide
under cursors A and B. The slide also can be used to move cursor A or B. The statistics are displayed
under the slide. They display the starting time, the sampling interval, the number of data items, and the
maximum and minimum values of the graph. They also display the maximum, minimum, and mean values
between cursors A and B; these data are updated automatically when the cursors are moved.
You can double-click the graph to open a dialogue box. This dialogue box can be used to customize the
style of the graph.
And you can also open a context menu by right-clicking the graph (this is impossible on the graph of the
data displayed in real time).
You can zoom on the graph with the mouse:
To zoom:
1. Press the left mouse button and drag the cursor to select the zone to be displayed.
2. Release the mouse button.
To cancel the zoom, right-click the graph to open a context menu, then select Undo Zoom.
