Without a reproducible example that includes some sample data (fake is
fine), the code you used, and some clear idea of what output you
expect, it's impossible to figure out how to help you. Here are some
suggestions for creating a good reproducible example:

A formula such as: as.Date('1900-01-01')+excel_date-1 should convert the
serial value to a date value.

Given a data frame, I'm trying to graph multiple lines on one graph, each

y2 - sample(1:50,5)

Try this:
ggplot(mydf,aes(x)) +

geom_line(aes(y = y2, colour = y2)) +
scale_color_manual(values = c(y1 = green4, y2 = blue2))
Note that you don't need to use `mydf` and names in the manual scale
should match the values in the aes() calls.

I think that the Cox model still works well when the only information
in the censoring is conditional on variables in the model. What you
describe could be called non-informative conditional on x.
To really see the difference you need informative censoring that
