chart:data-source-has-labels

[Regina Henschel <regina.henschel@libreoffice.org>]

Hi Members,

for tomorrow:

The <chart:plot-area> element (11.5) has the deprecated attributes 
chart:data-source-has-labels (19.17 in ODF 1.3) and 
table:cell-range-address (19.597.6 in ODF 1.3).

The attribute table:cell-range-address (19.597.6 in ODF 1.3) is removed 
in ODF 1.4. with OFFICE-3741.

Suggestion:
a) Remove chart:data-source-has-labels attribute (19.17 in ODF 1.3) too
b) Use OFFICE-4134 to track this.

Reasoning: The chart:data-source-has-labels attribute is already 
deprecated in ODF 1.2, see OFFICE-3326. The attribute is only defined in 
relationship to the now deleted table:cell-range-address attribute 
(19.597.6 in ODF 1.3).

======================================

These two attributes were used to determine an ersatz for a missing or 
incomplete <chart:categories> element (11.10).

Current text in 11.10:
The <chart:categories> element represents labels that are displayed on a 
category-axis.
This element may have a table:cell-range-address attribute that 
specifies a range from which category labels are taken. If this 
attribute or the <chart:categories> element itself is omitted, the 
chart:data-source-has-labels attribute of the <chart:plot-area> element 
should be evaluated for labels to display on a category-axis.

Because both, the element <chart:categories> and its only attribute 
table:cell-range-address, are optional, we need to specify a new ersatz.

Suggestion for 11.10:
The <chart:categories> element represents labels that are displayed on a 
category-axis.
If the <chart:categories> element itself or its attribute 
table:cell-range-address (19.597.2) is omitted, the numbers 1, 2, 3, â 
may be used as labels.

LibreOffice and Excel use numbers 1, 2, 3, â as labels on the axis in 
such case. Google shows no labels. Can please someone with Linux test, 
what Gnumeric does in such case? A test file is attached.

======================================

The current text in 19.597.2 is:
The table:cell-range-address attribute specifies the source from which 
the category labels are taken. If this attribute or the 
<chart:categories> element is omitted the chart:data-source-has-labels 
19.17 attribute of the <chart:plot-area> 11.5 element should be evaluated.

This too needs to be changed because of the no longer existing attribute 
chart:data-source-has-labels. Because the ersatz is already described in 
<chart:categories> element, I think we simply delete the sentence.

Suggestion for 19.597.2:
The table:cell-range-address attribute specifies the source from which 
the category labels are taken.

======================================

OFFICE-4134 contains already a solution for chart:series-source 
attribute (20.54).

Kind regards,
Regina
