Max X Value for Time Plots

[mtanco]

How can we, in a time plot, set the x_max value to be our largest number. It only takes a float, and converting to unix numbers doesn't seem to work:

from datetime import datetime

Convert the string to a datetime object

timestamp_str = "2020-05-04T10:22:21"
timestamp_dt = datetime.strptime(timestamp_str, "%Y-%m-%dT%H:%M:%S")

Convert the datetime object to a Unix timestamp (int)

unix_timestamp = int(timestamp_dt.timestamp())
