python 3.x - Plotting Pandas: Grouped line chart -


i have pandas dataframe in following format:

groups  value 1       0 0       0 0       0 0       0.1 1       0.4 1       0.5 0       0.5 1       0.8 0       0.8 1       0.9 1       1 1       1 1       1 1       1 0       1 0       1

i want sorted line plot has value in y-axis, shown here:

example graph

anyway: want similar line each group in same plot well. (or 2 lines groups, differ in size)

can me out? reckon thats possible?

i use python 3.x pandas 0.16.2. i'd prefer using matplotlib or seaborn.

import pandas pd import numpy np import matplotlib.pyplot plt  df = pd.read_csv('/home/jian/downloads/real_data.csv')  # processing # ========================== fig, ax = plt.subplots() ax.set_ylim([0, 1.2]) count = 0  def func(group):     group.sort('value', inplace=true)     x = np.linspace(0, 1, len(group))     global ax, count     if count > 0:         ax.plot(x, group.value, label=group.groups.values[0])     count += 1     return group  df.groupby('groups').apply(func) ax.legend(loc='best')
