Comparison of different coordinate axis curves

[zhang-zimin]

What should I do if the coordinate axes of the two curves are different? For example, one of them is a logarithmic axis.

[cjekel]

If one curve has a log axis and the other curve doesn't, you'll need to transform one of the two curves such that they are both on the same axis.

You should be able to notice when one curve is on a different axis because it should have a larger error (or distance). You can confirm this by taking one curve, transforming one of the axis, and comparing this transformed curve with the original curve.

It is okay if both curves have a single logarithmic axis, assuming it is the same one.

Does this help a bit?
