Using a Slicer on a Pivot Table and Regular Chart (Non-Pivot Chart)

Good Afternoon -

I am trying to use three slicers for both a pivot table and for a chart that was created off the source data of the pivot table. I cannot use a pivot chart as the chart I created was a Gantt chart and a pivot chart does not allow me to customize the stacked bar chart enough to represent a Gantt chart view.

So far the only thing I have been able to do is make 3 slicers for the pivot table and 3 slicers for the chart, even though the slicers contain the same data. Is it possible to link these into one slicer or since it is not a pivot chart is that not possible?

Thank you,

Tyler
