Plotting utils¶
A few useful helper functions
-
mesmerize.plotting.utils.get_colormap(labels: iter, cmap: str, **kwargs) → collections.OrderedDict[source]¶ Get a dict for mapping labels onto colors
Any kwargs are passed to auto_colormap()
- Parameters
labels – labels for creating a colormap. Order is maintained if it is a list of unique elements.
cmap – name of colormap
- Returns
dict of labels as keys and colors as values
-
mesmerize.plotting.utils.map_labels_to_colors(labels: iter, cmap: str, **kwargs) → list[source]¶ Map labels onto colors according to chosen colormap
Any kwargs are passed to auto_colormap()
- Parameters
labels – labels for mapping onto a colormap
cmap – name of colormap
- Returns
list of colors mapped onto the labels
-
mesmerize.plotting.utils.auto_colormap(n_colors: int, cmap: str = 'hsv', output: str = 'mpl', spacing: str = 'uniform', alpha: float = 1.0) → List[Union[PyQt5.QtGui.QColor, numpy.ndarray]][source]¶ If non-qualitative map: returns list of colors evenly spread through the chosen colormap. If qualitative map: returns subsequent colors from the chosen colormap
- Parameters
n_colors – Numbers of colors to return
cmap – name of colormap
output – option: ‘mpl’ returns RGBA values between 0-1 which matplotlib likes, option: ‘pyqt’ returns QtGui.QColor instances that correspond to the RGBA values
spacing – option: ‘uniform’ returns evenly spaced colors across the entire cmap range option: ‘subsequent’ returns subsequent colors from the cmap
alpha – alpha level, 0.0 - 1.0
- Returns
List of colors as either QColor or numpy array with length n_colors
-
class
mesmerize.plotting.utils.WidgetRegistry[source]¶ Register widgets to conveniently store and restore their states
-
register(widget: PyQt5.QtWidgets.QWidget, setter: callable, getter: callable, name: str)[source]¶ Register a widget. The setter and getter methods must be interoperable
- Parameters
widget (QtWidgets.QWidget) – widget to register
setter (callable) – widget’s method to use for setting its value
getter (callable) – widget’s method to use for getting its value. This value must be settable through the specified “setter” method
name (str) – a name for this widget
