How to add deadlines to a chart

Hello. I am trying to do:

• Create a chart when users made withdrawals (payments)
• Add to this chart the dates (deadlines) when users are prohibited from making any withdrawals (payments)

What I have:

• Withdrawal (payment) events when users have performed them
• An array of dates (deadlines) in user properties.

What I did:

1. Created line chart in segmentation
2. Added event  withdrawal to the chart 
3. When I try to add dates to the chart from the user properties, I get nothing

What I expected:

Any idea how I can solve it maybe in the other way,  because I think the chart does not support it ?

I will be very grateful for any help
