Hi,
I am creating the attached chart in Jupyter notebook. I had seen that you should change the type of the xaxis to “category” to get rid of the weekend gaps. It seems to have worked for the OHLC subplot but not for the volume bar chart. How do I remove the gaps in the bar chart?
Thanks,
Rob
Below is the code I’m using (Python3):
import plotly.graph_objects as go
import pandas_ta as ta
from datetime import datetime, timedelta
import pandas as pd
import yfinance
from plotly.subplots import make_subplots
from plotly.offline import init_notebook_mode
from plotly.io import write_image
init_notebook_mode()amzn = yfinance.Ticker(‘AMZN’).history(‘max’)
start = (datetime.now() - timedelta(days=90)).strftime(‘%Y-%m-%d’)
end = datetime.now().strftime(‘%Y-%m-%d’)
amzn.ta.willr(append=True)
amzn.ta.sma(length=7, append=True)
amzn.ta.sma(length=20, append=True)
fig = make_subplots(rows=3, cols=1,
shared_xaxes=True,
vertical_spacing=0.05,
subplot_titles=(‘OHLC’, ‘Volume’,“Williams %R”),
row_heights = [1000,500,500],
)fig.add_trace(go.Ohlc(x=amzn.loc[start:end].index,
open=amzn.loc[start:end][‘open’],
high=amzn.loc[start:end][‘high’],
low=amzn.loc[start:end][‘low’],
close=amzn.loc[start:end][‘close’],
name=‘OHLC’),
row=1,col=1)fig.add_trace(go.Bar(x=amzn.loc[start:end].index,
y=amzn.loc[start:end][‘volume’],
showlegend=False),
row=2, col=1)sma7 = go.Scatter(x=amzn.loc[start:end].index,
y=amzn.loc[start:end][‘SMA_7’],
mode=‘lines’,
name=‘SMA 7’)
fig.add_trace(sma7, row=1, col=1)sma20 = go.Scatter(x=amzn.loc[start:end].index,
y=amzn.loc[start:end][‘SMA_20’],
mode=‘lines’,
name=‘SMA 20’)
fig.add_trace(sma20, row=1, col=1)fig.add_trace(go.Scatter(x=amzn.loc[start:end].index,
y=amzn.loc[start:end][‘WILLR_14’],
showlegend=True),
row=3,
col=1)fig.update_layout(xaxis={‘type’: ‘category’},xaxis_rangeslider_visible=False, width=1000, height=800)
write_image(fig, “/home/rob/tmp/chart.png”,format=‘png’)
fig.show()
