About bode plot horizontal axis question

[klmnopq]

I have a question

I'm wondering in bode plot

we write the horizontal axis w rad/sec

what does this mean?
is it normal scale 0.1 0.2 0.3 ... etc with equal distances?? it's clear not because it's drwan on semilog paper

if it's the horizontal log w

why then we write 0.1 ,0.2 ,,1 , 10... etc?
we should then write the logaritmic value corresponding -1 ,0 , 1 ...

what's the horizontal axis?

* if i want to see w=10 rad/sec
I'll search at horizontal corresponding to w=10 ?
or I will serrch the horizontal on w=1? "log 10=1"?

waiting answer
thanks in advance

x-axis in bode plots are logarithmic. Different computer programs use different notation, MATLAB for instance gives such a plot:

Which is a "Scientific notation".
So w=0.1 equal 10^-1, w=1 equal 10^0, w=10 equal 10^1. w=100 equal 10^2 etc. in the plot above.
