Question

我有这样的df：

     bnw_Percent  bnw_Value  mtgp_Percent  mtgp_Value  php_Percent  php_Value  
0      0.004414    1.48150      0.010767     2.03548     0.028395    3.91826

我正在用以下代码制作一个情节：

plot=df.plot(x=['bnw_Value', 'mtgp_Value', 'php_Value'], y=['bnw_Percent', 'php_Percent', 'mtgp_Percent'],  title='Frequency Distribution of Fuzzy Accumulated Values')
plot.set_xlabel('Value')
plot.set_ylabel('Percent')
plot.legend(loc='center left', bbox_to_anchor=(1, 0.5))

看起来像这样：

我的问题是这导致重叠的x轴值，我真正想要的是bnw_Value，mtgp_Value或php_Value中的最小值和最大值在这三列中的任何一列中，以10为增量。或者至少x轴可以某种方式读取。

Answer 1

你可以这样做：

df.plot(x=df[[col for col in df.columns if 'Value' in col]].min(axis=1),
        y=['bnw_Percent', 'php_Percent', 'mtgp_Percent'],
        title='Frequency Distribution of Fuzzy Accumulated Values')

说明：

In [24]: [col for col in df.columns if 'Value' in col]
Out[24]: ['bnw_Value', 'mtgp_Value', 'php_Value']

In [25]: df[[col for col in df.columns if 'Value' in col]].min(axis=1)
Out[25]:
0      1.48150
1      5.44825
2      9.41501
3     13.38180
4     17.34850
5     21.31530
6     25.28200
7     29.24880
8     33.21550
9     37.18230
10    41.14910
11    45.11580
12    49.08260
13    53.04930
14    57.01610
15    60.98280
16    64.94960
17    68.91640
18    72.88310
19    76.84990

Answer 2

添加轮换（例如20）：

plot=df.plot(x=['bnw_Value', 'mtgp_Value', 'php_Value'], 
             y=['bnw_Percent', 'php_Percent', 'mtgp_Percent'],  
             rot=20,
             title='Frequency Distribution of Fuzzy Accumulated Values')
