I am having problems when I want to make a graph about public transport in Argentina, the label is displayed on the graph, what can I do to fix it?

Also, if I don´t use the instruction .show the graph is made twice, without the label upon it, but twice, so I have to choose between two graphs, both which look awful

I’ve tried changing the order of the instructions, investigated here at StackOverflow, searched at https://seaborn.pydata.org/generated/seaborn.objects.Plot.layout.html and https://seaborn.pydata.org/generated/seaborn.objects.Plot.label.html

But I haven´t found anything that solves this problem
