106 Parameters
107 ----------
108 data : `~pandas.core.frame.DataFrame`
109 The catalog containing various rho statistics.
110 plotInfo : `dict`, optional
111 A dictionary of information about the data being plotted with keys:
112 ``"run"``
113 The output run for the plots (`str`).
114 ``"skymap"``
115 The type of skymap used for the data (`str`).
116 ``"filter"``
117 The filter used for this data (`str`).
118 ``"tract"``
119 The tract that the data comes from (`str`).
120 **kwargs
121 Additional keyword arguments to pass to the plot
123 Returns
124 -------
125 fig_dict : `dict` [`~matplotlib.figure.Figure`]
126 The resulting figures.
127 The figure corresponding :math:`\rho_1(\theta)` can be accessed
128 with the key `rho1` and similarly for the other rho statistics.
129 :math:`\rho_3'` is accessed with the key `rho3alt`.
131 Examples
132 --------
133 An example rho statistics plot may be seen below:
