postpic.plotting package

The plot subpackage should provide an interface to various plot backends.

Submodules

postpic.plotting.plotter_matplotlib module

This package provides the MatplotlibPlotter Class.

This Class can be used to plot Field Objects using the matplotlib interface.

class postpic.plotting.plotter_matplotlib.MatplotlibPlotter(reader, outdir='./', autosave=False, project=None, ext='png', size_inches=(9, 7), dpi=160, facecolor=(1, 1, 1, 0.01), transparent=False)

Bases: object

Provides Methods to modify figures and axes objects for convenient plotting. It also autogenerates savenames and annotates the plot if a reader is given. A reader can be a dumpreader or a simulationreder.

class LinearSegmentedColormap(name, segmentdata, N=256, gamma=1.0)

Bases: matplotlib.colors.Colormap

Colormap objects based on lookup tables using linear segments.

The lookup table is generated using linear interpolation for each primary color, with the 0-1 domain divided into any number of segments.

static from_list(name, colors, N=256, gamma=1.0)

Make a linear segmented colormap with name from a sequence of colors which evenly transitions from colors[0] at val=0 to colors[-1] at val=1. N is the number of rgb quantization levels. Alternatively, a list of (value, color) tuples can be given to divide the range unevenly.

set_gamma(gamma)

Set a new gamma value and regenerate color map.

static addField2d(figax, field, log10plot=True, interpolation='none', contourlevels=array([], dtype=float64), saveandclose=True, xlim=None, ylim=None, clim=None, savecsv=False, lineoutx=False, lineouty=False, **kwargs)

lastsavename()

returns the last savenme. If there wasnt a last a new savename is created.

matplotlib = <module 'matplotlib' from '/usr/lib/python3/dist-packages/matplotlib/__init__.py'>

plotField(field, autoreduce=True, maxlen=6000, name=None, **kwargs)

This is the main method, that should be used for plotting.

plotField2d(field, name=None, **kwargs)

plotFields(*fields, **kwargs)

plotFields1d(*fields, **kwargs)

plotallderived(dumpreader)

plots all fields dumped.
