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. It has known limitations and implementation details may change.
