Dynamic culling

Is it possible to make the culling Dynamic in on brush of sub-chart ?? I could not access the culling property ..How can i access it from the chart object ?

Start by tracing how the sub-chart brush accesses the chart object and where the culling property is defined. The issue does not name files or tests; done means establishing whether culling can be changed dynamically during sub-chart brushing and how it can be accessed from the chart object.
