Regina, I looked at the xml in Gnumeric.
It indicates it as follows:
<style:style ...>
<style:chart-properties chart:interpolation="gnm:step-end".../>
</style:style>
I guess the 'gnm:step-end' is a foreign element/attribute. Should I
implement something similar for LO ? If yes, what to use instead of
"gnm:". If no, can you point me in the right direction.
if what you implement has the same semantics as what Gnumeric does (and
i think that's your goal) then it does make sense to use the same
foreign elements.
you'd need to add a namespace declaration for the "gnm" prefix; look at
the xmlns:gnm="..." attribute that must be somewhere in the file (likely
on the root element). you can add namespaces in
xmloff/inc/xmloff/xmlnmspe.hxx and SchXMLExport::SchXMLExport() in
xmloff/source/chart/SchXMLExport.cxx.
I'm not sure whether the namespace it necessary for an attribute
_value_. Currently the attribute "chart:interpolation" allows only the
values none, cubic-spline and b-spline. Gnumeric does not introduce a
new attribute or element, but a new value for the attribute.
I'm not sure whether the way Gnumeric does it, is grammatically correct.
Perhaps it is necessary to make an own attribute
"LOchart:interpolation", which then allows more values. Thorsten might
know it, and you should ask him.
Kind regards
Regina
