Tabs: Graph - Axes Appearance - Time Axis - Signal Axis - Signals - Gradient & Auxiliary Signals - Auxiliary Signal Details - MS Spectra

Sets scale of display and units for signal (vertical) axis of graph. Both the signal name and signal units are exclusive to the signal displayed and are taken (by default) from the Device Setup dialog of the detector.

Graph Properties - Signal Axis

Visible

Enables the display of the vertical axis.

Override Signal Units

Allows to manually enter units which will be displayed on the y-axis of the graph. When unchecked (default), signal units set in the System Configuration dialog will be used.

Title

Name of the axis.

Units Type

Type of the units of the axis displayed in square brackets.

Fixed

Numbers will always be displayed on the vertical axis in the units stated in the Units field without regard to size. When changing the range of the axis the numbers are not normalized and thus no prefix is added to the units.

Auto

Numbers will be displayed on the vertical axis in the normalized basic units stated in the Units field. The vertical axis is thus automatically normalized. This means that in the case of necessity, prefixes expressing multiples of 1000 or fractions of the basic units are added to the basic units. For example, instead of the value 0.001 V the value 1 mV will be displayed.

Prefix

Sets the prefix for the Units if the Auto option for Units Type is selected.

Units

The type of units entered (e.g. V (Volts), RI (Refractive Index),… ). The conversion between the implicit units (volts) and your own units is entered with the help of the fields Offset and Scale while the Fixed option for Units Type is selected. When Auto option is selected, only the basic units (without prefixes) should be entered.

Offset & Scale

Offset

Displayed data will be shifted by the value entered here. This applies to the graph signal axis only and not to the result tables.

Scale

Displayed data will be multiplied by the value entered here. This applies to the graph signal axis only and not to the results tables.

Original

Sets original values (i.e. Offset to 0 and Scale to 1).

Range

Fixed

Fixed range of the vertical axis of the graph. This means that the range is determined by the From and To parameters and not by the actual size of the chromatogram.

From and To

Values for fixed range on vertical axis.

Get Current

The From and To fields are filled in by the minimum and maximum voltage of the active chromatogram (signal) according to the current selection.
