Which two statements ate true about a dvt:gauge component? (Choose two.)
A.
dvt:thresholdSet with dvt:threshold tags can be used to define ranges of data and coloring for a
gauge.
B.
The style of the dial in a dial gauge is fixed.
C.
A gauge component can render as a vertical status meter.
D.
Gauge data range must start from 0.
Explanation:
A: A Threshold represents a significant value range like quota, target or limit value etc. When the indicator falls
into one of the threshold ranges, it means certain criteria have been met or not. Different threshold ranges in
gauges may have different colors, which you may customize.
C: The Vertical Status Meter and Status Meter are meters with a rectangular indicator placed in a bounding
box. It looks like a mercury barometer.
Incorrect Answers:
B: The Indicator shows the metric value of the Gauge. There are three types of indicators for Dial Gauges: Line,
Needle and Fill. Line and Needle are rotating pointers to show the metric value by pointing to certain angle on
the dial. The Needle indicator is thicker than the Line indicator. Fill is a slice or section of the dial that fills from
the minimum value up to the metric value. Users may specify the indicator fill color and border color.
D: The simplest data model for a Gauge is a single metric value, which can be specified by the value attribute.
In addition, the threshold, minimum and maximum values can also be specified by Threshold tag, and the
minValue and maxValue attributes respectively.
