ZingChart: Is it possible to generate a 180-degree pie chart?
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,
...
}
