Graph Properties - Time Axis tab

Sets the scale of the display and the units for time on the horizontal axis of graph.

Graph Properties - Time Axis

Visible

Enables the display of time axis.

Title

Name of the axis.

Units Type

Type of units of the axis, displayed in square brackets. Following unit types are available:

Auto - Numbers will be displayed on the axis by the normalized basic units stated in the Units field. The axis is thus automatically normalized. This means that, when necessary, suffixes expressed in multiples of 1000 or fractions of the basic units are added to the basic units.

Fixed - Numbers will always be displayed on the axis in the units stated in the Units field without regard to size. Whenever a change of the range of the axis occurs, the numbers are not normalized and thus no prefix is added to the units.

Use Instrument settings - Units will be taken from the System Configuration - Instrument Units of the respective instrument.

Time - seconds - The axis will be displayed in seconds.

Time - minutes - The axis will be displayed in minutes and their hundredths.

Time - H:M:S - The axis will be displayed in hours, minutes and seconds.

Time - hours - The axis will be displayed in hours.

Units

By selecting Auto or Fixed in the Units Type field, you can enter the units in which you wish to display the horizontal axis. The conversion between the implicit units (minutes) and your own units is entered with the help of the Offset and Scale fields. When the Units Type is switched to Auto, only basic units without prefixes can be entered.

Offset & Scale

Offset

Displayed data will be shifted by the value entered here.

Scale

Displayed data will be multiplied by the value entered here.

Original

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

Note:

This settings applies to the graph axis only and not to the results tables. Consequently, only simplified peak tags will be shifted, while enhanced peak tags will keep the original values, as they are derived from result table.

Range

Fixed

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

From, To

Values for fixed range on horizontal axis.

Get Current

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