There exists no attribute hide/show in ODF. But you can use the chart
properties chart:symbol-type and chart:data-label-foo and the graphic
properties draw:fill and draw:line. They can all be set to "none". A toggle
need not be in the legend, but can be at the series directly. One problem is,
to keep the previous settings, so that they can be restored. Another problem is
to decide, what state is to be stored. All properties are available via API, so
a solution as extension is possible too.
