Excel graph, exponentil axis

[Julien Rivard]

Hello,
I am trying to produce a graph with an exponential X axis.
More particularly with a power of 1.85.
I am not able to put the semi logarithmic graph in the negative.
Is there a solution?
See the following chart that I'm trying to reproduce

+Thanks for your help
