Plotting tools for visualization

Source code

General Attributes and Methods

pointAdvection.tools.from_cpt(filename, use_extremes=True, **kwargs)[source]

Reads GMT color palette table files and registers the colormap to be recognizable by plt.cm.get_cmap()

Can import HSV (hue-saturation-value) or RGB values

Parameters:

filename: str: color palette table file
use_extremes: bool, default True: use the under, over and bad values from the cpt file
**kwargs: dict: optional arguments for LinearSegmentedColormap

pointAdvection.tools.custom_colormap(N, map_name, **kwargs)[source]

Calculates a custom colormap and registers it to be recognizable by plt.cm.get_cmap()

Parameters:

N: int

number of slices in initial HSV color map

map_name: str

name of color map

'Joughin': [Joughin2018] standard velocity colormap

'Rignot': [Rignot2011] standard velocity colormap

'Seroussi': [Seroussi2011] velocity divergence colormap

**kwargs: dict

optional arguments for LinearSegmentedColormap
