The point chart can be an XY plot such as the one shown in this figure.
Each point in an XY point series contains two data values: x and y. Each point is visualized as a point marker.
The point markers in an XY point series or the series can have a border, fill effect, shape, size, and depth. Settings at the point level would have precedence. Assigning null for a border or fill effect indicates that the property is unset. Size is measured in model units. Depth is measured relative to the floor grid cell (0 = no width, 1 = width of floor grid cell).
For more information on the point series object in the API, refer to the PointSeries class.
