熊猫数据框：如何绘制烛台

Question

I have following data in dataframe to plot candlesticks.

     open   high    close   low
date                
2013-10-08  3.21    3.28    3.27    3.20
2013-10-09  3.25    3.28    3.26    3.22
2013-10-10  3.26    3.27    3.23    3.21
2013-10-11  3.25    3.28    3.27    3.23
2013-10-14  3.28    3.35    3.31    3.26

I tried to use candlestick_ohlc function from matplotlib.finance, but it seems that somehow I needed to change the data type of the index 'date'. I am new to python, still trying to figure out a way.

Any help would be appreciated, thank you.

Answer 1

If the index is not a datetime (use df.index.dtype to find out which type it is), you can change the type to a datetime by using:

df.index = pd.to_datetime(df.index)

(assuming your dataframe is called df )
