* [DLC]

* stat parameters
Parameters
----------
df_stats : pandas.DataFrame
plot_chans : dict
Dictionary of channels to be plotted. Key is used for the plot title,
value is a list of unique channel names that will be included for
the statistic values. For example,
plot_chans['$B123 M_x$'] = ['blade1-blade1-node-003-momentvec-x',
'blade2-blade2-node-003-momentvec-x']
fig_dir_base : str
Base directory of where to store all the figures. A new sub-directory
will be created for each DLC.
labels : list, default=None
Labels used in the legend when comparing various DLB's
figsize : tuple, default=(8,6)
dlc_ignore : list, default=['dlc00']
By default all but dlc00 (stair case, wind ramp) are plotted. Add
more dlc numbers here if necessary.
run_dirs : list, default=None
If run_dirs is not defined it will be taken from the unique values
in the DataFrame. The order of the elements in this list needs to be
consistent with labels, sim_ids (if defined).
sim_ids : list, default=[]
Only used when creating the file name of the figures: appended at
the end of the file name (which starts with the unique channel name).
chans_ms_1hz : dict, default={}
Key/value pairs of channel and list of to be plotten m values. Channel
refers to plot title/label as used as the key value in plot_chans.
