Zoom
Calibration curves can be zoomed as often as required by spanning an
area of the curve display from the top left to the bottom right with the left
mouse button held down. Zooming can be undone by spanning an area
from the bottom right to the top left or using the context-sensitive Show
all menu command.
NOTE
When a new determination is selected the complete calibration curve is
always shown, i.e., the zoom range is not retained when the determi-
nation is changed.
Context-sensitive menu items for graph
