pyqtgraph issue[BUG]

Requirements (place an x in each of the [ ])**

• I realize finplot is not a web lib. (Hint: it’s native!)
• I’ve read the snippets and not found what I’m looking for.
• I’ve searched for any related issues and avoided creating a duplicate issue.
• I’ve updated finplot (pip install -U finplot).
• I’ve supplied the required data to run my code below.

Code to reproduce

import pandas as pd
import finplot as fplt
df = pd.DataFrame({"open": [100, 105, 95, 99, 92],
                   "high": [110, 120, 115, 110, 115],
                   "low": [92, 90, 85, 70, 81],
                   "close": [105, 95, 99, 92, 85],
                   "volume": [10, 12, 5, 1, 15],
                   },
                  index=pd.date_range("2020-01-01", "2020-01-05"))
ax, ax2 = fplt.create_plot("XXX", rows=2)  # create two axes plot
cols_for_candles = ['open', 'close', 'high', 'low']
cols_for_volume = ['open', 'close', 'volume']
df_candles = df[cols_for_candles]
fplt.candlestick_ochl(df_candles, ax=ax)
df_volume = df[cols_for_volume]
fplt.volume_ocv(df_volume, ax=ax2)
fplt.show()

Describe the bug

I’ve read topics in Discussions and Issues and there is one common issue among them - pyqtgraph. I have updated pyqtgraph to version 0.13.1 recently. And the version of finplot is 1.8.4. After the pyqtgraph update finplot doesn’t work - I got this error whenever I run any code that worked fine previously before the update.

AttributeError: module 'pyqtgraph.Qt.QtGui' has no attribute 'QApplication'

Expected behavior

There is no error while running finplot.

Screenshots

Reproducible in:

OS: windows 10 finplot version: 1.8.4 pyqtgraph version: 0.13.1 pyqt version: 5.15.7 pyqt5-qt version: 5.15.2 pyqt5-sip version: 12.11.0 pyqt5webengine version: 5.15.6

I had the same problem today, when I upgraded python 3.79 to 3.86 and updated several libraries, I solved it using this method:

pip3 install pyqtgraph = = 0.12.4
