in a graph, fill base line both -infinity and infinity

[tda*!]

Hello,

In a graph is it possible to fill base line to both negative infinity and positive infinity?

Thanks

Could you explain what you are imagining this to look like?  If the plot color was red and you could fill this to both -infinity and +infinity then the whole graph would be colored red...

If you meant for the colors to be different an easy work around is to the set either the -infinity or +infinity and then color the background of the graph to the other color:
