Subject: [OASIS Issue Tracker] (OFFICE-3883) [chart] Proposal: chart legend size


     [ https://issues.oasis-open.org/browse/OFFICE-3883?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Stahl updated OFFICE-3883:
----------------------------------
    Proposal: 
1. RATIONALE

1.1 Use cases:
   Size of chart legends cannot be controlled in ODF 1.2. The size
   is automatically calculated, it can expand vertically, horizontally,
   or to both directions controlled by respective attributes. Sometimes
   it is desirable to use fixed legend size and/or resize the legend
   manually. Therefore this proposal suggests including svg:width and
   svg:height into the attribute list of chart:legend element when 
   style:legend-expansion attribute is "custom". In this case 
   style:legend-expansion-aspect-ratio attribute should be the proportion of
   svg:width and svg:height. This also improves interoperability with 
   Office Open XML.

1.2 Alternatives considered:
   None.

2. REQUESTED CHANGES TO THE ODF STANDARD

2.1 Text changes/additions:
   Update 11.3 chart:legend section as following:

   The <chart:legend> element has the following attributes: chart:legend-align 19.22, chart:legend-position 19.23, chart:style-name 19.27, style:legend-expansion 19.492, style:legend-expansion-aspect-ratio 19.493, svg:height 19.541.2, svg:width 19.573.3, svg:x 19.575.1 and svg:y 19.579.1
   
   Add new subsections:

   19.541.2 <chart:legend>
   The svg:height attribute defines the height of the legend.
   The svg:height attribute is usable with the following element: <chart:legend> 11.3.
   The svg:height attribute has the data type length 18.3.18.
   
   19.573.3 <chart:legend>
   The svg:width attribute defines the width of a plot-area.
   The svg:width attribute is usable with the following element: <chart:legend> 11.3.
   The svg:width attribute has the data type length 18.3.18.
   
2.2 Schema changes/additions:

3. IMPACTS

3.1 Conformance:
   This proposal will not add any mandatory features or behaviors.

3.2 Backwards compatibility:
   This element was not available in previous versions and is
   optional. Existing ODF processors may ignore it.

3.3 Accessibility impact:
   None.
