Add Legend to Seaborn point plot

Question

I am plotting multiple dataframes as point plot using seaborn  Also I am plotting all the dataframes on the same axis    How would I add legend to the plot    My code takes each of the dataframe and plots it one after another on the same figure   Each dataframe has same columns   date        count 2017-01-01  35 2017-01-02  43 2017-01-03  12 2017-01-04  27    My code    f  ax   plt subplots 1  1  figsize figsize  x col  date  y col    count  sns pointplot ax ax x x col y y col data df 1 color  blue   sns pointplot ax ax x x col y y col data df 2 color  green   sns pointplot ax ax x x col y y col data df 3 color  red     This plots 3 lines on the same plot  However the legend is missing  The documentation does not accept label argument    One workaround that worked was creating a new dataframe and using hue argument   df 1  region      A  df 2  region      B  df 3  region      C  df   pd concat  df 1 df 2 df 3   sns pointplot ax ax x x col y y col data df hue  region     But I would like to know if there is a way to create a legend for the code that first adds sequentially point plot to the figure and then add a legend   Sample output

Old question  but there s an easier way   sns pointplot x x col y y col data df 1 color  blue   sns pointplot x x col y y col data df 2 color  green   sns pointplot x x col y y col data df 3 color  red   plt legend labels   legendEntry1    legendEntry2    legendEntry3      This lets you add the plots sequentially  and not have to worry about any of the matplotlib crap besides defining the legend items

I would suggest not to use seaborn pointplot for plotting  This makes things unnecessarily complicated  Instead use matplotlib plot date  This allows to set labels to the plots and have them automatically put into a legend with ax legend     import matplotlib pyplot as plt import pandas as pd import seaborn as sns import numpy as np  date   pd date range  2017-03   freq  M   periods 15  count   np random rand 15 4  df1   pd DataFrame   date  date   count    count   0    df2   pd DataFrame   date  date   count    count   1  0 7   df3   pd DataFrame   date  date   count    count   2  2    f  ax   plt subplots 1  1  x col  date  y col    count   ax plot date df1 date  df1  count    color  blue   label  A   linestyle  -   ax plot date df2 date  df2  count    color  red   label  B   linestyle  -   ax plot date df3 date  df3  count    color  green   label  C   linestyle  -    ax legend    plt gcf   autofmt xdate   plt show        In case one is still interested in obtaining the legend for pointplots  here a way to go   sns pointplot ax ax x x col y y col data df1 color  blue   sns pointplot ax ax x x col y y col data df2 color  green   sns pointplot ax ax x x col y y col data df3 color  red    ax legend handles ax lines   len df1  1   labels   A   B   C     ax set xticklabels  t get text   split  T   0  for t in ax get xticklabels     plt gcf   autofmt xdate    plt show

I tried using Adam B s answer  however  it didn t work for me  Instead  I found the following workaround for adding legends to pointplots   import matplotlib patches as mpatches red patch   mpatches Patch color   bb3f3f   label  Label1   black patch   mpatches Patch color   000000   label  Label2     In the pointplots  the color can be specified as mentioned in previous answers  Once these patches corresponding to the different plots are set up    plt legend handles  red patch  black patch     And the legend ought to appear in the pointplot
