## Is there a difference between log value and semi log value?

I am trying to create a linear graph and semi log graph. I have question that is there a difference between semi log values and log values  .example x=10, and log vlaue= lets say 1, what will be the semilog! or is it just same. semi log just used to differentiate log-log plot( both axis have log values) to semi-log plot ( one axis have log and another is normal)?

Does this help:

https://en.wikipedia.org/wiki/Semi-log_plot

In science and engineering, a semi-log plot/graph or semi-logarithmic plot/graph has one axis on a logarithmic scale, the other on a linear scale. It is useful for data with exponential relationships, where one variable covers a large range of values, or to zoom in and visualize that - what seems to be a straight line in the beginning - is in fact the slow start of a logarithmic curve that is about to spike and changes are much bigger than thought initially.
