Are there any vba functions to change the data displayed in the data area of
the chart and/or legend text through VBA (ie not using the wizard, instead
need to do this in code)?

Specifically, I would like to put checkboxes on a worksheet to enable the
user to turn on-and-off data that's displayed in a chart (there's about 10
stats they could choose from, and it gets busy if all are shown).

Thanks!
