无法作图-说'x'的值不是列名

如何解决无法作图-说'x'的值不是列名

我正在尝试绘制此时间序列图（一些股票报价器的RSI图表）。但是，我似乎根本无法获得Plotly的图表！并向我抛出以下错误：

Value of 'x' is not the name of a column in 'data_frame'. Expected one of ['Date','AAPL','GOOGL','IBM','MSFT'] but received: index To use the index,pass it in directly as **df.index**.

我认为问题是由于数据帧造成的？并且它具有“多层索引”？

下面是我必须生成一个数据框并从那里进行绘图的代码。我使用了x=data.index,y=RSI.columns，但似乎不起作用。

#List to store my ticker codes
ticker = ['AAPL','MSFT']

#other variables
wrsi = ['EWMA']
mwa = 14
startdate = "2019-01-01"
enddate = "2020-10-31"

#pull data
data = web.DataReader(ticker,'yahoo',startdate,enddate)

#RSI calculation
delta = data['Adj Close'].diff(1)
delta.dropna(inplace=True)

positive = delta.copy()
negative = delta.copy()

positive[positive < 0] = 0
negative[negative > 0] = 0

#wrsi is ewma or sma?
if wrsi == 'sma':
    average_gain = positive.rolling(mwa).mean()
    average_loss = abs(negative.rolling(mwa).mean())
else:
    average_gain = positive.ewm(span=mwa).mean()
    average_loss = abs(negative.ewm(span=mwa).mean())
    
relative_strength = average_gain / average_loss
RSI = 100-(100/ (1+ relative_strength))


#plot chart
fig = px.line(RSI,x=data.index,y=RSI.columns,title='Time Series with Range Slider and Selectors')

fig.update_xaxes(
    rangeslider_visible=True,rangeselector=dict(
        buttons=list([
            dict(count=1,label="1m",step="month",stepmode="backward"),dict(count=6,label="6m",dict(count=1,label="YTD",step="year",stepmode="todate"),label="1y",dict(step="all")
        ])
    )
)
fig.show()

解决方法

错误原因是x轴上的数据与y轴上的数据不同。
