Declaration

property ShowNeedle: Boolean read; write; default True;

Property Value

Type	Default
Boolean	True

Remarks

The needle is the indicator that shows the arc scale’s current Value. This property is useful if you need to hide the needle in order to use the scale as a part of the composite multi-functional dashboard, consisting of several nested scales. If the ShowNeedle property is set to True, the needle is displayed on top of the scale; otherwise, the needle is hidden:

The ShowNeedle Property Value	Example
True
False

Note

In order to create composite multi-functional dashboards from individual scales, you may need to hide additional displayed elements of the scale, such as labels, tick marks, and optionally, both the spindle cap and background. Refer to the Scale Visual Elements topic for additional information.

The default value of the ShowNeedle property is True.
