Hello @strikar21,

Volume Profile

Volume Profile is rather tricky, not just for plotting but also where to start the calculation and how many observations aka width: int = 10 (default) to use. So you can not just pass it to mpf.make_addplot(stck.VP,color='y',type = 'line', panel = 1). There is some post processing required.

Volume Profile and Matplotlib Finance Charting

Currently Matplotlib Finance does not have Volume Profile Charting, though it is a proposed feature request mplfinance Issue #162. If you want Matplotlib Finance to support Pandas TA Volume Profile, please let them know by adding onto Issue #162.

Volume Profile, Post Processing and Matplotlib Charting

Here is the code I use to visually verify Volume Profile with Matplotlib.

vpdf = df.tail(30) # Take the last 30 Daily Bars
vp = vpdf.ta.vp() # Run Volume Profile
print("Returns unsorted close\n", vp, "\n") # Visual Table Check

# Set the index to mean_close and in ascending order
vp['mean_close'] = round(vp['mean_close'], 2)
vp.set_index('mean_close', inplace=True)
vp.sort_index(ascending=True, inplace=True)
print("Sorted by mean_close\n", vp, "\n") # Visual Table Check

# Take the last three columns and plot them with horizontal bars
vp[vp.columns[-3:]].plot(
    kind='barh', 
    figsize=(5, 8),
    title="SPY VP (Recent 30 Days)",
    color=['green', 'red', 'silver'],
    alpha=0.45,
    stacked=True,
)

Is there an easier way to plot this with Matplotlib yet?
