Graph Ranges

The range of each signal can be selected as either 'Auto' or 'Fixed'.

Auto: the trend line of that signal will display the maximum value at the top of the graph. The Y-axis will be automatically calibrate to the maximum value achieved.

Fixed: the display will be scaled against the relevant value entered as the Range.

The graph shown below illustrates the difference between an analogue signal set at Auto and when set at Fixed.

The blue trend line (temperature) is set at  Fixed and ranged 0-100 ^oC, the Y-axis has therefore also been automatically scaled 0-100.

The purple trend line (conductivity) is set to Auto and the Y-axis has automatically been re-scaled 0-51.

The maximum value achieved was 50 mS/cm, the red vertical time line position is the 'real time' value of analogue readings, (shown along the bottom of the graph.)
