obspy.imaging.waveform.WaveformPlotting

class WaveformPlotting(**kwargs)[source]

Bases: builtins.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__ str(object=’‘) -> str
__module__ str(object=’‘) -> str
__weakref__ list of weak references to the object (if defined)

Public Methods

plot Plot the Traces showing one graph per Trace.
plotDay DEPRECATED: ‘plotDay’ has been renamed to
plotSection DEPRECATED: ‘plotSection’ has been renamed to
plotWaveform DEPRECATED: ‘plotWaveform’ has been renamed to
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. It either saves the

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
_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
_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

Special Methods

__del__ Destructor closes the figure instance if it has been created by the
__dir__ default dir() implementation
__format__ default object formatter
__init__ Checks some variables and maps the kwargs to class variables.
__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().
