No, log is working correctly
Linear:
Log:
For the log view, compare the distance between 0.6 and 0.65 (bottom) to the distance between 1.05 and 1.1 (top). Both are a distance of 0.05, but the bottom is obviously further apart, as would be expected for log scale.
If this is not sufficiently clear, then use ylim([0.25 1.1]) for the two modes, and you will see for log that the data is crowded into the top
