我有这个数据框：

pd.DataFrame({'Depth': {0: 0.2,
  1: 0.4,
  2: 0.4,
  3: 0.4,
  4: 0.4,
  5: 0.4,
  6: 0.6000000000000001,
  7: 0.4,
  8: 3.2,
  9: 2.0},
 'DateTimeUTC': {0: Timestamp('2018-03-28 06:25:08'),
  1: Timestamp('2018-03-28 06:25:49'),
  2: Timestamp('2018-03-28 06:27:06'),
  3: Timestamp('2018-03-28 06:32:11'),
  4: Timestamp('2018-03-28 06:32:59'),
  5: Timestamp('2018-03-28 06:34:02'),
  6: Timestamp('2018-03-28 06:35:38'),
  7: Timestamp('2018-03-28 06:37:04'),
  8: Timestamp('2018-03-28 06:39:08'),
  9: Timestamp('2018-03-28 06:40:52')}})

看起来像这样：

pd.DataFrame({'Depth': {0: 0.2,
  1: 0.4,
  2: 0.4,
  3: 0.4,
  4: 0.4,
  5: 0.4,
  6: 0.6000000000000001,
  7: 0.4,
  8: 3.2,
  9: 2.0},
 'DateTimeUTC': {0: Timestamp('2018-03-28 06:25:08'),
  1: …

我想散布以下pandas.DataFrame的前两列，第三列作为颜色值。

>>>df = pd.DataFrame({'a': {'1128': -2, '1129': 0, '1146': -4, '1142': -3, '1154': -2,
 '1130': -1, '1125': -1, '1126': -2, '1127': -5, '1135': -2},
 'c': {'1128': 5300, '1129': 6500, '1146': 8900, '1142': 8900,
 '1154': 9000, '1130': 5600, '1125': 9400, '1126': 6000, '1127': 7200,
 '1135': 7700}, 'b': {'1128': -3, '1129': -10, '1146': -6, '1142': -3,
 '1154': -7, '1130': -2, '1125': -7, '1126': -7, '1127': 0, '1135': -1}}


>>>df
        a   b   c
did         
1125    -1  -7  9400
1126    -2  -7  6000
1127 …
