--- Comment #3 from Clarence GUO <clarence.guo.bj@gmail.com> ---
The chart in the sample is not a standard chart but a composite chart.
Series 1, 2 and 4 are percent stacked columns which were applied to the main Y
axis, while series 3 is normal column which was applied to the secondary Y
axis. So series 3 will cover some part of Series 1, 2 and 4.
MS Office supports such chart. It can set one or more data series to another
chart type. AOO's UI cannot do this. But the chart kernal function supports. So
when open the sample file the chart looks OK. However, the ODF format doesn't
support this, that why after save the sample to ods and reopen, the chart
becomes incorrect(Series 3 occupy 100% space of the percent stacked column).
The reason is AOO defined a style 'ch4' and applied to <chart:plot-area>. In
this style, the chart:percentage attribute was set to true. This attribute
specifies a percentage accumulation of values per category. Because this style
was applied to <chart:plot-area>, then all data series are regarded as percent
columns. And series 3 is a unique data series which applied to the secondary Y
axis. So it occpy the total 100% space so that other data series are all
covered.
If want to fix this defect, must move chart:percentage attribute from the style
which applied to <chart:plot-area> to the style which applied to
<chart:series>. However, for this attribute, ODF 1.2 says "This attribute is
evaluated for chart styles that are applied to a <chart:plot-area> element.".
So my requirement is conflict with the ODF standard.
Then how can I fix this defect? It seems the only way is to change the standard
and change the corresponding filter code. But I know change the standard is not
easy...
