Choosing Scale Units

Select Options ® Global options to call up the Global Options dialog window.

The Scale Units option allows you to determine how the scale numbering along the vertical axis of the graph is described by the scale units key at the top.

Normally, for example, if your data values are all in the thousands, the scale numbering is displayed without the three rightmost places. A key appears above the numbers giving scale units (thousands, millions, and so on). You can use the Scale Units option to determine how this key is displayed.

One of the scale unit types Text string, E+nn or Technical must be active at any given time. The following table gives the display value for each type, when a data value has (is greater than or equal to) the scale given in the left-hand column.

The three possible Scale Units options only affect scale units for fractional values between 10 -12 and 10 +12 . For numbers outside this range, the scale units key automatically changes to exponential format. You cannot turn this off.
