mooonpy.tools.misc_utils module

miscellaneous utilities that do not belong anywhere else

class mooonpy.tools.misc_utils.ColorMap(name='coolwarm', low=0.0, high=1.0)[source]

Bases: ListListTable

Read csv files of RGB values with a similar format to matplotlib.colormaps. root/tools/lookups contains some example custom colormaps, more can be added by adding files to this directory.

Currently Supported Colormaps

  • coolwarm: blue to light to red diverging map (same as matplotlib?)

  • cooloverwarm: blue to grey to red diverging map

  • coswan: pink to grey to green diverging map

  • pyrolyze: green to grey to dark purple diverging map

  • redblack: red to dark grey linearish map

Read csv files of RGB vales into a ListListTable object.

mooonpy.tools.misc_utils.auto_colorbar(fig, axs, colormap, step, low=None, high=None, shrink=None, pad=None, label='', orientation='vertical', kwargs=None)[source]
mooonpy.tools.misc_utils.calculate_axis_ticks(data_min, data_max, ax=None, xaxis=True, tick_range=(5, 9), allowed_spacings=None, raise_error=True)[source]

Calculate optimal axis limits and tick positions.

Parameters

data_minfloat

Lower limit (usually 0)

data_maxfloat

Maximum data value to accommodate

tick_rangetuple of int, optional

(min_ticks, max_ticks), default (5, 9)

allowed_spacingslist of float, optional

Acceptable tick spacings, default [5, 10, 25, 50, 100, 200, 250]

Returns

ticksndarray

Array of tick positions

limitfloat

Upper axis limit

spacingfloat

Spacing between ticks

Raises

ValueError

If no valid tick configuration exists

mooonpy.tools.misc_utils.inc_arrange(low, high, step)[source]
mooonpy.tools.misc_utils.reset_axis_limits(ax: Axes, x: bool = True, y: bool = True, view: str | None = None, style: str | List[str] | None = None, xtick_spacing: float | None = None, ytick_spacing: float | None = None) → None[source]

Reset axis limits based on plotted line data with optional view presets and styling.

Parameters:

axmatplotlib.axes.Axes

The axes object to modify

xbool

Tighten x-axis limits to limit of data(default: True)

ybool

Tighten y-axis limits to limit of data(default: True)

viewstr, optional

Preset view configurations: - ‘q1’: First quadrant (x_min=0, y_min=0) - ‘q2’: Second quadrant (x_max=0, y_min=0) - ‘q3’: Third quadrant (x_max=0, y_max=0) - ‘q4’: Fourth quadrant (x_min=0, y_max=0) - ‘+x’: Positive x (x_min=0, uses y parameter) - ‘-x’: Negative x (x_max=0, uses y parameter) - ‘+y’: Positive y (y_min=0, uses x parameter) - ‘-y’: Negative y (y_max=0, uses x parameter)

stylestr or list of str, optional

Styling options: - ‘equal’: Equal aspect ratio (ax.axis(‘equal’)) - ‘square’: Square plot area (ax.axis(‘square’)) - ‘scaled’: Scaled aspect ratio (ax.axis(‘scaled’)) - ‘tight’: Tight layout (ax.axis(‘tight’)) - ‘auto’: Auto scaling (ax.axis(‘auto’)) - ‘off’: Turn off axis (ax.axis(‘off’)) - ‘on’: Turn on axis (ax.axis(‘on’)) - ‘equalticks’: Equal tick spacing with locked aspect ratio - ‘box’: Add box around plot (ax.set_frame_on(True)) - ‘nobox’: Remove box (ax.set_frame_on(False)) - ‘grid’: Add grid (ax.grid(True)) - ‘nogrid’: Remove grid (ax.grid(False)) Can pass a single string or list of strings for multiple styles

xtick_spacingfloat, optional

Major tick spacing for x-axis (uses MultipleLocator)

ytick_spacingfloat, optional

Major tick spacing for y-axis (uses MultipleLocator)
