如何从列表中绘制数据?

我正在筛选数据列表。我需要绘制每个源节点的结果。这是我的数据模式:

 ('timestamp', 'node_source', 'node_destination', 'node_source_counter_acces_to_specific_function')

在plt.xlabel标签我想贴时间戳。在plt.ylabel公司我想放柜台。在图例中,我想根据目的地地址放置标记。每一行都是我的数据集非常重要。我正在使用此函数:

import matplotlib.pyplot as plt

list_info= [('1547977394', '02141592cc0000000100000000000000', '02141592cc0000000500000000000000', '1'),

例如,必须绘制并可视化到node_source:02141592cc0000000100000000000000的预期数据是:

('02141592cc0000000100000000000000',timestam':[1547977395,1547977396,1547977397,1547977398,1547977399,1547977403],'Counter':[2,3,4,5,6,10],'dest':[02141592cc0000000300000000000000,02141592cc0000000500000000000000,02141592cc0000000700000000000000,02141592cc0000000300000000000000,02141592cc0000000500000000000000,02141592cc0000000500000000000000])

plots = dict()

# create dictionary like this: plots[source]={'timestam': list of integer timestamps, 'counter': list of integer counter, 'dest': list of destinations}
for i, el in enumerate(list_info):
    if el[1] in plots:
        plots[el[1]]['timestam'].append(int(el[0]))
        plots[el[1]]['counter'].append(int(el[3]))
        plots[el[1]]['dest'].append(el[2])
    else:
        plots[el[1]]={'timestam': [int(el[0])], 'counter': [int(el[3])], 'dest': [el[2]]}

# iterate over elements in 'plots', sort by timestamp, plot
for i in plots:
    y = [x for _,x in sorted(zip(plots[i]['timestam'],plots[i]['counter']))]
    labels = [x for _,x in sorted(zip(plots[i]['timestam'],plots[i]['dest']))]
    x = sorted(plots[i]['timestam'])
    plt.plot(x, y, label=', '.join(labels), marker='o') # label=... creates the legend entry
plt.xlabel('timestamp')
plt.ylabel('counter')
plt.title('some data')
plt.legend() # add legend
plt.show()

结果:

result

(如果list_info已按时间戳排序,则无需排序。)

编辑:

# iterate over elements in 'plots', sort by timestamp, plot
f, ax = plt.subplots(len(plots), 1, sharex=True)
for i, item in enumerate(plots):
    y = [x for _,x in sorted(zip(plots[item]['timestam'],plots[item]['counter']))]
    labels = [x for _,x in sorted(zip(plots[item]['timestam'],plots[item]['dest']))]
    x = sorted(plots[item]['timestam'])
    ax[i].plot(x, y, c='k') # label=... creates the legend entry
    for j, _ in enumerate(x):
        ax[i].scatter(x[j], y[j], label=labels[j])
    ax[i].legend() # add legend
    ax[i].set_ylabel('counter')
plt.xlabel('timestamp')
plt.show()

结果:

result
