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 ObsPyStream
orTrace
objects.It uses matplotlib to plot the waveforms.
Attributes

__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().
