Hi all!

Hope you are doing good. I have a question about the Nelson aalen cumulative hazard function. I made a graph about chance of discharge after a certain surgery.
As you can see in the exported graph does the graph begin at day 5, how can change it so it begin at 0 with a probablity of 0? I can change the labels of the axis but there will be no line drawn from 0.
The graph looks the way it does because there is no chance of discharge in the first 4 days. I hope you understand my question! Let me know if you know how to help

Kind regards,
Daniel
