-Pandas DataFrame conversion
-===========================
-
-A [Pandas DataFrame](https://pandas.pydata.org/docs/getting_started/intro_tutorials/01_table_oriented.html#min-tut-01-tableoriented) is a python data structure allowing powerful table processings.
-
-## Export as dataframe
-
-[TimeStampedBuffer](../../argaze.md/#argaze.DataStructures.TimeStampedBuffer) instance can be converted into dataframe provided that data values are stored as dictionaries.
-
-```python
-from argaze import DataStructures
-
-# Create a timestamped data buffer
-ts_data = DataStructures.TimeStampedBuffer()
-
-# Store various data as dictionary
-ts_data[10] = {"A_key": 0, "B_key": 0.123}}
-ts_data[20] = {"A_key": 4, "B_key": 0.567}}
-ts_data[30] = {"A_key": 8, "B_key": 0.901}}
-...
-
-# Convert timestamped data buffer into dataframe
-ts_buffer_dataframe = ts_buffer.as_dataframe()
-```
-
-ts_buffer_dataframe would look like:
-
-|timestamp|A_key|B_key|
-|:--------|:----|:----|
-|10 |0 |0.123|
-|20 |4 |0.567|
-|30 |8 |0.901|
-|... |... |... |
-
-## Import from dataframe
-
-Reversely, [TimeStampedBuffer](../../argaze.md/#argaze.DataStructures.TimeStampedBuffer) instance can be created from dataframe, as a result of which each dataframe columns label will become a key of data value dictionary. Notice that the column containing timestamp values have to be called 'timestamp'.
