13.2. Axes

13.2.1. Introduction to Axes

Description Axes are reference points to

curves in a chart. Dran-View

will normally display time

(most charts), duration

(magnitude-duration charts), or

frequency (DFT charts) along

the X-axes (horizontal) while

displaying values of channels

along the Y-axes (vertical).

Terms Both X- and Y-axes are displayed as a thick line with thinner, longer and shorter

lines protruding from it. The longer lines are called main ticks, each of which is

accompanied by a value label, a number representing a point on the axis. The

shorter lines are known as sub-ticks, and do not have value labels next to them.

Most axes, with the exception of standard time axes, also display a unit label to

their top/right. Some Y-axes also have a longer explanation label next to them.

Zooming is used in this text to mean that the scale, such as the distance between

two main ticks, has changed. Zooming out will indicate that this distance is

increasing, while zooming in will imply that it's decreasing. Panning will mean that

the scale is unchanged, but the start and end points of the axis are changing.

Adding,

Deleting

and Moving

Axes

Axes can only be moved within the chart, i.e. you cannot move an axis from one

chart to another. To move an axis, select it in order to see the selection rectangle

around it, then bring the pointer onto the boundaries of the rectangle. The pointer

should now look like this . You can now click and drag the axis to the desired

location. A tracking rectangle will appear to aid this click and drag action.

Axes are created and destroyed as needed. If channels are added or removed, the

stack mode is changed or modified, or the X-Axis per site option is toggled. Hence,

axes cannot be added except as side effects of other actions. Deleting an axis, either

through the axis' property page or by selecting it and pressing the delete key or

selecting Cut from the pop-up menu or the edit menu (Enterprise Edition only), will

disable all channels associated with the axis.
