I'm expecting a graph to show me the value of the ATR indicator but I do not know how to plot the indicator. I thought that it would show under the strategy equity graph but it did not show up. Could anyone help me to figure out how to chart the indicator in a plot.

class WildFire(QCAlgorithm):

def Initialize(self):
self.SetStartDate(2020, 6, 19) # Set Start Date
self.SetCash(100000) # Set Strategy Cash
self.AddEquity("SPY", Resolution.Minute)
self.atr = self.ATR("SPY", 14)

def OnData(self, data):
'''OnData event is the primary entry point for your algorithm. Each new data point will be pumped in here.
Arguments:
data: Slice object keyed by symbol containing the stock data
'''
# print (self.atr.Current.Value)
# if not self.Portfolio.Invested:
# self.SetHoldings("SPY", 1)

#self.PlotIndicator("ATR", self.atr.Current.Value)
self.Plot("My Indicators", "ATR Signal", self.atr.Current.Value)
