9.5.29 Vacuum Gauge

A Vacuum Gauge is the same as a Gauge, but the needle will move clockwise

with decreasing pressure.

9.5.30 Wind Angle

The wind angle component is similar in appearance to traditional mechanical

wind angle gauges. An outline of a boat’s hull appears in the center of the

component, and a red needle points directly into the wind. The gauge is labeled

in increments to 30 degrees with intermediate tick marks at 10 degree intervals,

from 0 degrees at the top to 180 degrees at the bottom on both port and

starboard sides. The areas on the scale between 20 degrees and 60 degrees

are colored red on the port side and green on the starboard side. The wind

speed appears in a small digital display in the lower part of the circular gauge. A

user-defined title appears at the top of the component, and the units of the wind

speed measurement appear in the lower-right hand corner of the component.

The wind angle component is square in aspect ratio; that is, a wind angle

component that is four grids high will also be four grids tall. An example of a wind

angle component is shown below.

Figure 63 – Wind Angle Component Example

Min Max Markers may be added to a Wind Angle Component by clicking on a

check box in the Component Editor. The markers show the limits of the needle

movement in either direction. These marks are associated with the control itself.

That means that if two controls are displaying the same data, each will maintain

its own values for the min max marks, and they can be reset independently.
