Have a problem, when I work with external_axes

Question

I need to add to the plot some text and I tried to use your guide "How to use your own matplotlib Figure and Axes in mplfinance". But i have an error:

"ValueError: make_addplot() ax kwargs must all be of type matplotlib.axis.Axes"

My code:


    import mplfinance as fplt
    import pandas as pd
    
    df5M = pd.read_csv("D:\\_users_files\\Kirill\\WORK\\fx2youcom\\df5M.csv", index_col=0, parse_dates=True)
    
    
    fig = fplt.figure(style='yahoo', figsize=(10.8, 6.4))
    
    ax1 = fig.add_subplot(2, 2, 1)
    
    sma = [fplt.make_addplot(df5M['SMA20'].tail(100), color='#f1afe1'),
           fplt.make_addplot(df5M['SMA50'].tail(100), color='#ffaf6c'),
           fplt.make_addplot(df5M['SMA200'].tail(100), color='#f0dea7')]
    
    fplt.plot(df5M.tail(100),
              type='candle',
              ax=ax1,
              style='yahoo',
              title="long_name",
              ylabel='5 Minutes',
              addplot=sma
              )
    fig

Is there an example of the output you expect? How do you want to add the text? Also, you specify subplots, do you want to specify 'SMA20', 'SMA50', 'SMA200', and 'candle'? — r-beginners, Jun 06 '21 at 14:14

Whenever you pass an external Axes object into mplfinance.plot() using the ax= kwarg, then

if you want to plot volume, then you must pass an Axes object in for the volume:
that is, instead of volume=True do volume=axes where axes is an Axes object on which you want to plot the volume.
you must also use kwarg ax= for all calls to mplfinance.make_addplot()

This information was noted at the bottom of the subplots page.
Probably should also be included in the external axes notebook.
