Re: [Matplotlib-users] plt scale x-axis by constant factor f

[Benjamin R. <ben...@ou...>]

I am not sure I understand. I took your question as "how do I make my x
tick labels show values as [0, 300] when my values really are [0, 3000]?".
Are the indexes you speak of ranging from 0 to 3000? If so, I don't see how
our examples aren't sufficient. As for formatting x "because it is not
defined", what is not defined? The formatting or x?
