obspy.imaging.waveform.WaveformPlotting

class WaveformPlotting(**kwargs)[source]

Bases: object

Class that provides several solutions for plotting large and small waveform data sets.

Warning

This class should NOT be used directly, instead use the plot() method of the ObsPy Stream or Trace objects.

It uses matplotlib to plot the waveforms.

Attributes

__dict__

__doc__

__module__

__weakref__

list of weak references to the object (if defined)

Public Methods

plot

Plot the Traces showing one graph per Trace.

plot_day

Extend the seismogram.

plot_section

Plots multiple waveforms as a record section on a single plot.

plot_waveform

Creates a graph of any given ObsPy Stream object.

Private Methods

Warning

Private methods are mainly for internal/developer use and their API might change without notice.

_WaveformPlotting__dayplot_get_min_max_values

Takes a Stream object and calculates the min and max values for each pixel in the dayplot.

_WaveformPlotting__dayplot_normalize_values

Normalizes all values in the 3 dimensional array, so that the minimum value will be 0 and the maximum value will be 1.

_WaveformPlotting__dayplot_set_x_ticks

Sets the xticks for the dayplot.

_WaveformPlotting__dayplot_set_y_ticks

Sets the yticks for the dayplot.

_WaveformPlotting__get_mergable_ids

_WaveformPlotting__get_merge_id

_WaveformPlotting__plot_min_max

Plots the data using a min/max approach that calculated the minimum and maximum values of each “pixel” and then plots only these values.

_WaveformPlotting__plot_set_x_ticks

Goes through all axes in pyplot and sets time ticks on the x axis.

_WaveformPlotting__plot_set_y_ticks

_WaveformPlotting__plot_straight

Just plots the data samples in the self.stream.

_WaveformPlotting__sect_fraction_to_offset

Helper function to return fractions from offsets

_WaveformPlotting__sect_init_color

Define the color of each trace

_WaveformPlotting__sect_init_plot

Function initialises plot all the illustration is done by self.plot_section()

_WaveformPlotting__sect_init_time

Define the time vector for each trace

_WaveformPlotting__sect_init_traces

Arrange the trace data used for plotting.

_WaveformPlotting__sect_normalize_traces

This helper function normalizes the traces

_WaveformPlotting__sect_scale_traces

The traces have to be scaled to fit between 0-1., each trace gets distance-range/num_traces space.

_WaveformPlotting__setup_figure

The design and look of the whole plot to be produced.

_add_zoomlevel_warning_text

_draw_overlap_axvspan_legend

_draw_overlap_axvspans

_plot_dayplot_scale

Plots the dayplot scale if requested.

_plot_event

Helper function to plot an event into the dayplot.

_remove_zoomlevel_warning_text

_time_to_xvalue

_warn_on_xaxis_zoom

Method to be used as a callback on method=fast, “minmax”-type plots to warn the user when zooming into the plot.

Special Methods

__del__

Destructor closes the figure instance if it has been created by the class.

__dir__

Default dir() implementation.

__format__

Default object formatter.

__init__

Checks some variables and maps the kwargs to class variables.

__init_subclass__

This method is called when a class is subclassed.

__new__

Create and return a new object.

__reduce__

Helper for pickle.

__reduce_ex__

Helper for pickle.

__sizeof__

Size of object in memory, in bytes.

__subclasshook__

Abstract classes can override this to customize issubclass().
