The graph are shown on the screen and can be printed.
The scales can be changed...
More than one sensor can be 'overlaid', even though the sensors are from different loggers with data recorded at different dates and times The first sensor selected will use the left hand axis - other sensors can use their own right hand axes.
The scales can be 'reset' back to the the maximum and minimum values in the data, but also 'reset' scale can be set for each sensor so that it can quickly be returned to a known scale.
Each sensor can be plotted using its own colour and line style - see Graph Options for details
