# Resolved: Why the X axis of Y vs Log(X) goes from 14.5 to 17.5?

Good morning. When you show the plot of Y vs X, the X axis goes from about 0.5 to about 4.0. Then, when we pass to Y vs Log(X), I expect that Log(x) goes from about Log(0.5)=-0.69 to Log(4.0)=1.39. So why it goes from 14.5 to 17.5 instead? Thank you

Hey Alessandro,

Thank you for your question!

Note that in the left figure (Y versus X) the X-axis goes, in fact, from about 0.5 x 10^7 to about 4.0 x 10^7. Transforming this axis by taking the (natural) log then results in the right figure (Y versus ln(X)) where the limits are from about ln(0.5 x 10^7) ~ 15 to about ln(4.0 x 10^7) ~ 17.5.

Hope this helps!

Kind regards,

Ok I didn't notice the "1e7" at the bottom. Thank you
