Hi,

Possible answer - on a log scale the increments are not equal distance
apart. Therefore a value of 75 is not halfway between 50 and 100. This is
the correct.

Cheers,

Some of the lower values, the start and stop of the bars, are ok. Some
higher values which appear in higher decades do not match the chart
values.
What is wrong and how should I fix it?
