Description: Following #4730 and #4867, this is a proposal to change the defaults for the upcoming 2.0 release regarding the default tick label formatting for log-scaled axes. This is not a finished PR, but mean to initiate discussion on whether this is desired as default (if not I still think a similar thing could be worth having as an option). A new default formatter (LogFormatterSciNotation) is used as default for all log-scaled axes. This formatter always prints all labels for the bases of the log scale (major ticks) and adds labels to the minor ticks as the axis view limits are made smaller (with a similar logic to LogLocator with subs=None): For less than 3 decades, (1, 3) * base**i are labeled. For less than 2 decades, (1, 2, 5) * base**i are labeled. For less than 1 decade, (1, 2, 4, 7) * base**i are labeled. The minor ticks are formatted in scientific notation: $ 3 \times 10^{-2} $ The base and exponent are omitted if the exponent is between -1 and 1: i.e., 0.1, 0.7, 1, 8, will be formatted as shown (as in #4730, this could be split as an option for all LogFormatter). Example of this formatter in action: The main motivation is to improve readability of the axis ticks when log-scaled axis are zoomed-in to less than a few decades, which under the current Formatters leaves only very few labels in the axis. Note that this does not change the formatting whenever more than 3 decades are spanned by the axis view limits.
