[office] proposals for charts: angle-offset, ring-hole,stock-chart-markers, hide-series

[Lars Oppermann <Lars.Oppermann@Sun.COM>]

Dear TC members,

I am forwarding the following four proposals created by the
OpenOffice.org-Chart development team concerning chart axes
for inclusion into OpenDocument 1.2...

----------------------------------------------------------------------

Chart: Angle Offset

Expand section 15.30.8 and rename it to 'Circle and Ring Properties'.

angle-offset

The attribute angle-offset can be used for charts with polar coordinate 
systems like circle, ring or radar charts. The given value is added to 
the mathematical zero angle position. Thus having a value of 90 degree 
the radial axis at minimum angle points to 12 o'clock position. The 
default value is 90 degree.

<define name="style-chart-properties-attlist" combine="interleave">
     <optional>
          <attribute name="chart:angle-offset">
             <ref name="nonNegativeInteger"/>
          </attribute>
     </optional>
</define>

----------------------------------------------------------------------

Chart: Ring Hole Size

Expand section 15.30.8 further:

hole-size

The attribute hole-size can be used for ring charts. It indicates how 
big the diameter of the hole is compared to the outer diameter of the 
outermost ring.

<define name="style-chart-properties-attlist" combine="interleave">
     <optional>
          <attribute name="chart:hole-size">
              <ref name="percent"/>
          </attribute>
     </optional>
</define>

----------------------------------------------------------------------

Chart: Stock Chart Markers

Correction: The current content of Chapter '10.14.1 Stock Chart Markers' 
is not a sub chapter of '10.14 Regression Curves'. Make it an own 
chapter 10.15 Stock Chart Markers instead.

----------------------------------------------------------------------

Chart: Hide Series

Generalize 15.31.2 Visibility by moving it from 15.31 Chart Axes 
Properties to 15.32 Common Chart Properties

Note, that there was no default before. And the description mentioned a 
non-existant axis-visible property.

     * Remove 15.31.2
     * Add:

15.32.4 Visibility

Some chart objects can be hidden without actually removing them. This 
can be done by setting the chart:visible property to false. This allows 
a temporary removal for objects with the option to re-display them. This 
property is allowed for chart:axis and chart:series elements.

For axes, this property is necessary to provide a chart with scaling 
information without displaying an actual axis object.

<define name="style-chart-properties-attlist" combine="interleave">
     <optional>
         <attribute name="chart:visible" a:defaultValue="true">
             <ref name="boolean"/>
         </attribute>
     </optional>
</define>
