For above example,
if object have 0 count for some of the states then i want to skip this
states from the chart object.
because it waste the unnecessary space in the chart and legend
and
Is their any way of setting the custom tooltip for given chart without
modifying the given object (in my example - without specifying null column
as tooltip) because doing this doing this object size increases...
