Is there a fixed limit on the number of data samples included in a Pie Chart ?
I understand that with many samples, smaller values will get lost in the chart, but at what point does canvasJS not bother rendering the sample because it’s too small or run out of colours to represent the samples ?
There is no limit on the number of data samples for pie/doughnut. CanvasJS tries to render every dataPoint. But when dataPoint’s segment becomes smaller than .1 pixel, it won’t be visible in most cases – limit should depends on browser’s implementation of Canvas.
