Line charts are made up of one or more series containing the same number of elements.

Each series is described by a legend (character string). A series is represented on a graphic by a succession of solid lines linking consecutive points.

Each point is formed by:

  • a (numerical) value on the Y-axis (the point's Y coordinate).

  • if required, a (character string) data label describing the value.

  • if required, a (numerical) error value associated with the value.

  • either an identical (character string) label for all points of the same position in each series.

  • or a (numerical) value on the X-axis, corresponding to the point's X coordinate.

The user defines the data for the graphic only when it is run. The data shown during the layout design phase is static and given merely by way of an example.
