Subject: [OASIS Issue Tracker] Commented: (OFFICE-2010)chart:class=chart:surface regression



    [ http://tools.oasis-open.org/issues/browse/OFFICE-2010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16888#action_16888 ] 

Dennis Hamilton commented on OFFICE-2010:
-----------------------------------------

Andreas: Got it.  And the chart:three-dimensional attribute is on a style that applies to <chart:plot-area>.  I shall declare myself incompetent around all of the interdepencies and variabilities of <chart:chart> and run screaming from the room now.  

(I'm not the one that says there's a 2-dimensional Cartesian coordinate system and I missed how this is like a topographical map with bands of z-axis altitudes projected onto that plane using topographical contour lines.  Well as I said, I didn't have the context.)

>             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
>          Issue Type: Bug
>          Components: Chart
>    Affects Versions: ODF 1.2
>            Reporter: Andreas Guelzow 
>            Assignee: Patrick Durusau
>             Fix For: ODF 1.2
>
>
> In ODF 1.1 the description for chart:class=chart:surface is:
> the data points are interpreted as tabular data, where each value defines a 'height' at a specific grid location. 
> In the ODF draft 1.2 this has changed to:
> The values of multiple <chart:series> (marked as being of type chart:surface) are interpreted as a 'altitude' at a specific grid location.
> So in 1.1 one needs only one series to give the tabular data (table range) for a whole surface where the column/row location indicates the grid location for this "height".
> In 1.2 on the other hands an undetermined number of series are supposed to be combined in an undetermined way to create the surface. (Some appear to interpret this to mean that each series gives the heights for one fixed coordinate and the series contains rather than tabular data a sequence of heights for the various values of the other coordinates.)
> As a consequence the 1.1 description allows several surface plot to be placed in the same chart. SInce there is no way to determine which series would belong to which surface, in 1.2 this has been removed.
