I'm trying to put together a composite graph, consisting of
both LineSeries and Column Series, for a financial page. I'm
rendering the entire graph inside of a ColumnChart. However, when
multiple points for the lineseries are close together, the
mouse-over only displays a single dataTip. When working in a
LineChart, multiple dataTips are displayed for any points close
together or on top of each other; is there any (preferably simple!)
way to replicate that functionality in a ColumnChart?
