OASIS Open Document Format for Office Applications (OpenDocument) TC

Hi,

while implementing the ODF 1.2 enhancements for the error category of 
business charts, OOo Chart's developer Björn Milcke noticed that one 
value in the "choice" for the chart:error-category is missing: the 
standard-error. It's a reasonable value, that some applications do 
support already.

He therefore proposed the following small enhancement:

In chapter "16.33.2 Error Category" add the following value to the 
choices for the error-category:

[..]

* Standard error (standard deviation of the mean) of a data series
  assuming an equal distribution

[..]




Best regards

Michael

"Standard
error (standard deviation of the mean) of a data series assuming an equal
distribution"

I believe "assuming a normal distribution"
is the typical wording.  In that case the standard error =  StandardDeviation/Sqrt(N)

[office] Proposal: Error bar category

Hi,


while implementing the ODF 1.2 enhancements for the error category of

business charts, OOo Chart's developer Björn Milcke noticed that one

value in the "choice" for the chart:error-category is missing:
the

standard-error. It's a reasonable value, that some applications do

support already.


He therefore proposed the following small enhancement:


In chapter "16.33.2 Error Category" add the following value to
the

choices for the error-category:


[..]


* Standard error (standard deviation of the mean) of a data series

  assuming an equal distribution


[..]



<define name="style-chart-properties-attlist" combine="interleave">

<optional>

   <attribute name="chart:error-category" a:defaultValue="none">

     <choice>

        <value>none</value>

        <value>variance</value>

        <value>standard-deviation</value>

        <value>percentage</value>

        <value>error-margin</value>

        <value>constant</value>

* new * <value>standard-error</value>

        <value>cell-range</value>

     </choice>
