Micro

By default the "%c" format specifier for scientific notation used to generate axis tick labels uses a lower case u as a prefix to indicate "micro" (10^-6). The set micro command tells gnuplot to use a different typographic character (unicode U+00B5). The byte sequence used to represent this character depends on the current encoding. See format specifiers (p. ), encoding (p. ).

This command is EXPERIMENTAL. Implementation details may change.
