Python 如何将非原始变量插入plotly express

到目前为止，我从红酒数据集中编辑了原始变量“quality”，如下所示：

wineData["is good"] = 0
wineData.loc[wineData["quality"]>=7,"is good"] = 1
#It is suggested to make the quality a binary variable. 
#Let's say for quality >= 7 is good quality or is good = 1 and for quality < 7 is not of good quality or is good = 0

import plotly.express as px
wineData = pd.read_csv('winequality-red.csv')
fig = px.bar(wineData, x="?", y="?", color="?", barmode="group")
fig.show()
