Several graphics primitives and Fig substitutes request ticks, miniticks, and tick labels. These are all interpreted the same way.
Ticks (or xticks/yticks) are notches on an axis that are usually labeled with their location. They may be specified in the following ways.
- *True*: same as -10 (below).
- *Positive number N*: draw exactly N ticks, including the endpoints. To subdivide an axis into 10 equal-sized segments, ask for 11 ticks.
- *Negative number -N*: draw at least N ticks. Ticks will be chosen with "natural" values, multiples of 2 or 5.
- *List of values*: draw a tick mark at each value.
- *Dict of value, label pairs*: draw a tick mark at each value, labeling it with the given string. This lets you say things like {3.14159: "pi"}.
- *False or None*: no ticks.
Miniticks (or xminiticks/yminiticks) are shorter notches without labels. They may be specified in the following ways.
- *True*: draw miniticks with "natural" values, more closely spaced than the ticks.
- *Positive number N*: draw exactly N miniticks, including the endpoints. To subdivide an axis into 100 equal-sized segments, ask for 101 miniticks.
- *Negative number -N*: draw at least N miniticks.
- *List of values*: draw a minitick mark at each value.
- *False or None*: no miniticks.
Tick labels (or xlabels/ylabels) are text labels next to each tick mark. To specify them explicitly, use the dict form of ticks (above). The "labels" option is usually a function or format string to convert numerical values to label strings.
- *True*: use the unumber function (described below)
- *Format string*: standard format strings, e.g. "%5.2f" for 12.34
- *Python callable*: function that converts numbers to strings
- *False or None*: no labels
A function that converts numbers to a Unicode string. Takes advantage of special Unicode characters to make nice minus signs and scientific notation.
