Hi

I have plotted a chart using a logarithmic scale - is it true to say
that on a logarithmic scale
the distance between the points are proportional - whereas on a linear
scale the distance between the figures are relative??

Thanks

In a word: NO

If you mean what I think you mean, then yes: the distance between 1 and
1.2 is the same as the distance between 100 and 120, or 5 and 6, or 15
and 18. It's a mathematical property of logarithms.
