utils.draw.AxisMultipleTicker¶

Class · Source

amticker = mdnc.utils.draw.AxisMultipleTicker(
    den_major=2, den_minor=5, number=np.pi, symbol=r'\pi'
)

Use multiple locator to define the formatted axis. Inspired by the following post:

https://stackoverflow.com/a/53586826

This class is a factory class, which could produce 3 properties used for formatting a special axis (like a trigonometric axis): formatter, major_locator, minor_locator. See the Examples to view how to use it.

Properties¶

formatter¶

amticker.formatter

The major formatter. Use the matplotlib API axis.set_major_formatter() to set it.

major_locator¶

amticker.major_locator

The major locator. Use the matplotlib API axis.set_major_locator() to set it.

minor_locator¶

amticker.minor_locator

The minor locator. Use the matplotlib API axis.set_set_minor_locator() to set it.
