addScatterLayer(xData, yData[, name[, symbol[, symbolSize[, fillColor[, edgeColor ]]]]])

Add a scatter chart layer to the XYChart.

A scatter chart can be considered as a special configuration of a line chart, in the data symbols are enabled and the line width is set to zero. Therefore only the data symbols are visible and the chart appears as scattered.
