The Structure of Charts 186
Wall and Floor
The chart wall is the background of the coordinate system where the data is plotted. Two
chart walls usually exist for 3D charts: one behind the plotted data and one as the left-hand
or right-hand demarcation. This depends on the rotation of the chart. 3D charts usually also
have a floor.
The Diagram object provides the properties Wall and Floor:
Wall (Object)
background wall of the coordinate system (supports
com.sun.star.chart.ChartArea
service)
Floor (Object)
floor panel of coordinate system (only for 3D charts, supports
com.sun.star.chart.ChartArea
service)
The specified objects support the com.sun.star.chart.ChartArea service, which provides the
usual fill and line properties (
and
com.sun.star.drawing.FillProperties
com.sun.star.drawing.LineProperties
services, refer to Drawings and Presentations).
The following example shows how graphics (named Sky) already contained in
OpenOffice.org can be used as a background for a chart. The wall is set to be blue.
