setScatterSerieShape - Associate a shape to a given scatter serie

This function allows you to associate a shape to a given scatter serie. A bunch of internal shapes are already defines (including circle, square and triangles). We may extend this to new shapes later on.

Calling this function

setScatterSerieShape($ScatterSeriesID,$Shape=SERIE_SHAPE_FILLEDCIRCLE);

Where :

ScatterSeriesID is the id of the scatter serie.

Shape is the name of a predefined shape.

The following shape are internally defined :

SERIE_SHAPE_FILLEDCIRCLE to associate a filled circle.

SERIE_SHAPE_FILLEDTRIANGLE to associate a filled triangle.

SERIE_SHAPE_FILLEDSQUARE to associate a filled square.

SERIE_SHAPE_FILLEDDIAMOND to associate a filled diamond.

SERIE_SHAPE_CIRCLE to associate a circle.

SERIE_SHAPE_TRIANGLE to associate a triangle.

SERIE_SHAPE_SQUARE to associate a square.

SERIE_SHAPE_DIAMOND to associate a diamond.
