It sure is! The aperture
property of the scaleR
object reduces the size of the pie chart by the specified number amount.
scaleR: {
aperture:180
},
The refAngle
property of the plot
object will flip the graph 180 degrees because the aperture will appear to cut the graph in a top down fashion.
plot: {
refAngle: 180,
...
}
