How to insert elbow connector across 3 excel charts and put into word doc?

How to insert elbow connector across 3 excel charts and put into word doc?

I can put the elbow connector line across the charts in excel but when i try to do this in word the elbow connector can only stay within one chart . It will not let me move the connector across all 3 charts.
Any ideas?
