Thanks for bringing this up @lotrus28 This part of the code is the least developed unfortunately. I'd be happy to see improvements/new functions added back to lifelines if you end...

This issue has useful bugs and information for me to improve lifelines, so I'd like to keep it open

Hi @arugola, It's not clear what the survival function _should_ be plotting, given time-varying (tv) covariates. Consider that the survival function measures points after some baseline measurement, so we have...

Suffice to say, there are fundamental problems with time varying covariates and prediction.

Hi @WenxiongLiao, it's a consequence of your data and the KM estimator. For the red curve, there is no data past ~70days. There's unfortunately not a good way to extrapolate...

Hi there, you should be able to pass in `color=...` into the function. Is that not working for you?

Hm, looks related to #1231. Can you try using the latest version of lifelines, v0.25.11? If you are using that, I think your solution is what should end up going...

Great! We'll incorporate it into the next release

Hi @WenxiongLiao, I'm not sure. Do you have an example dataset and code that demonstrates the difference?

Try `concordance.index(..., outx=FALSE)`
