Angle to which the radialBars should end. The sum of the startAngle and endAngle should not exceed 360.

offsetX: Number

Sets the left offset for radialBars

offsetY: Number

Sets the top offset for radialBars

hollow:

margin: Number

Spacing which will be subtracted from the available hollow size

size: String

image: String

Optional image URL which can be displayed in the hollow area.

imageWidth: Number

Width of the hollow image

imageHeight: Number

Height of the hollow image

imageOffsetX: Number

Sets the left offset of hollow image

imageOffsetY: Number

Sets the top offset of hollow image

imageClipped: Boolean

If true, the image doesn’t exceeds the hollow area and is contained within.

position: String

Available Options

front
back

dropShadow

enabled: Boolean

Enable a dropshadow for paths of the SVG

track:

show: Boolean

Show track under the bar lines.

startAngle: Number

Angle from which the track should start.
