Displaying gauge needle
In a Gauge visual, CDP Data Visualization helps you to display the measure mark as a needle or a line from the center to the measure value on the arc of a Gauge visual.
To show a gauge arrow from the center to the measure value on the arc, navigate to the Marks menu, and select Needle under the Key measure mark option. To remove the gauge needle select None. To show a gauge line instead of an arrow, select Line.
Note the Gauge needle in the second image after selecting this option.
