Some times we need to show source data with chart. we could turn it
true by use specific name in axis(xlcategory) or by using source data
's linking picture . Both of these could help us to show specific
series.
and as all of us know that, the chart's datatable will show all of the
series' value.
I want to know whether we can hide any dummy series in chart's data
table directly.

Thanks for your answer in advance.
