# pairs_plotting¶

This module provides R style pairs plotting functionality.

ema_workbench.analysis.pairs_plotting.pairs_scatter(experiments, outcomes, outcomes_to_show=[], group_by=None, grouping_specifiers=None, ylabels={}, legend=True, point_in_time=-1, filter_scalar=False, **kwargs)

Generate a R style pairs scatter multiplot. In case of time-series data, the end states are used.

Parameters: experiments (DataFrame) – outcomes (dict) – outcomes_to_show (list of str, optional) – list of outcome of interest you want to plot. group_by (str, optional) – name of the column in the cases array to group results by. Alternatively, index can be used to use indexing arrays as the basis for grouping. grouping_specifiers (dict, optional) – dict of categories to be used as a basis for grouping by. Grouping_specifiers is only meaningful if group_by is provided as well. In case of grouping by index, the grouping specifiers should be in a dictionary where the key denotes the name of the group. ylabels (dict, optional) – ylabels is a dictionary with the outcome names as keys, the specified values will be used as labels for the y axis. legend (bool, optional) – if true, and group_by is given, show a legend. point_in_time (float, optional) – the point in time at which the scatter is to be made. If None is provided (default), the end states are used. point_in_time should be a valid value on time filter_scalar (bool, optional) – remove the non-time-series outcomes. Defaults to True. fig (Figure instance) – the figure instance axes (dict) – key is tuple of names of outcomes, value is associated axes instance .. note:: the current implementation is limited to seven different – categories in case of column, categories, and/or discretesize. This limit is due to the colors specified in COLOR_LIST.
ema_workbench.analysis.pairs_plotting.pairs_lines(experiments, outcomes, outcomes_to_show=[], group_by=None, grouping_specifiers=None, ylabels={}, legend=True, **kwargs)

Generate a R style pairs lines multiplot. It shows the behavior of two outcomes over time against each other. The origin is denoted with a circle and the end is denoted with a ‘+’.

Parameters: experiments (DataFrame) – outcomes (dict) – outcomes_to_show (list of str, optional) – list of outcome of interest you want to plot. group_by (str, optional) – name of the column in the cases array to group results by. Alternatively, index can be used to use indexing arrays as the basis for grouping. grouping_specifiers (dict, optional) – dict of categories to be used as a basis for grouping by. Grouping_specifiers is only meaningful if group_by is provided as well. In case of grouping by index, the grouping specifiers should be in a dictionary where the key denotes the name of the group. ylabels (dict, optional) – ylabels is a dictionary with the outcome names as keys, the specified values will be used as labels for the y axis. legend (bool, optional) – if true, and group_by is given, show a legend. point_in_time (float, optional) – the point in time at which the scatter is to be made. If None is provided (default), the end states are used. point_in_time should be a valid value on time fig – the figure instance dict – key is tuple of names of outcomes, value is associated axes instance
ema_workbench.analysis.pairs_plotting.pairs_density(experiments, outcomes, outcomes_to_show=[], group_by=None, grouping_specifiers=None, ylabels={}, point_in_time=-1, log=True, gridsize=50, colormap='coolwarm', filter_scalar=True)

Generate a R style pairs hexbin density multiplot. In case of time-series data, the end states are used.

hexbin makes hexagonal binning plot of x versus y, where x, y are 1-D sequences of the same length, N. If C is None (the default), this is a histogram of the number of occurences of the observations at (x[i],y[i]). For further detail see matplotlib on hexbin

Parameters: experiments (DataFrame) – outcomes (dict) – outcomes_to_show (list of str, optional) – list of outcome of interest you want to plot. group_by (str, optional) – name of the column in the cases array to group results by. Alternatively, index can be used to use indexing arrays as the basis for grouping. grouping_specifiers (dict, optional) – dict of categories to be used as a basis for grouping by. Grouping_specifiers is only meaningful if group_by is provided as well. In case of grouping by index, the grouping specifiers should be in a dictionary where the key denotes the name of the group. ylabels (dict, optional) – ylabels is a dictionary with the outcome names as keys, the specified values will be used as labels for the y axis. point_in_time (float, optional) – the point in time at which the scatter is to be made. If None is provided (default), the end states are used. point_in_time should be a valid value on time log (bool, optional) – indicating whether density should be log scaled. Defaults to True. gridsize (int, optional) – controls the gridsize for the hexagonal bining. (default = 50) cmap (str) – color map that is to be used in generating the hexbin. For details on the available maps, see pylab. (Defaults = coolwarm) filter_scalar (bool, optional) – remove the non-time-series outcomes. Defaults to True. fig – the figure instance dict – key is tuple of names of outcomes, value is associated axes instance
