Radial Legend

Draws a numeric legend for a radial meter.  An example, with 5 numbers drawn, is shown here inside a Radial Indicator:

The black arc that runs from the minimum angle to the maximum angle and the vertical divider line based at the center of the arc, are displayed only while the system is in design mode. They will vanish as soon as the application is put into run mode.

The numbers will always be drawn horizontally.

 

The graphic editor dialog for a Radial Legend is shown in the following image:

Tag

Selecting a tag or parameter is an optional step.  If provided, the legend can take its minimum and maximum values from this tag or parameter’s value. (Normally, this will be the same tag or parameter that is used for the radial indicator).

Alternatively, you can ignore this field and specify minimum and maximum values for the display in the Scaling section.

Font

Select a font tag to control the font and other display parameters for the legend text.

Minimum Angle

Sets the starting angle of the legend display (left side). Measured in degrees, clockwise from vertical.  Defaults to 225 degrees.

Maximum Angle

Sets the end angle of the legend display (right side). Measured in degrees, clockwise from vertical.  Defaults to 135 degrees.

Number of Labels

Sets the number of labels to display in the legend. There is no minimum, but legends look best with at least 3.

Color

Opens the color selector where you can set the text color.

Counter-Clockwise

When checked, the legend will increase in a counter-clockwise direction.

Scaling

If a tag is specified, you can use that tag's scaling to set the beginning and end of the legend's range. Otherwise, you can use these fields to specify minimum and maximum values of your own.
