This question also has an answer here (in German):

I would like to say in German the following:
The first chart describes ..., the second one shows... .
My version:
Die erste Grafik beschreibt ..., die zweite zeigt ... .
I am not sure whether I should use die zweite or rather die Zweite (i.e. treat zweite as a “substantiviertes Adjektiv”).
