how to disable plotting resample data

stentor

Is there any way to disable plotting resample data? I tried and failed to figure it out.
thanks a lot!

Plotting of any data can be turned off using the plot parameter when you define your data feed (data is your resampled data feed):

data = bt.feeds.GenericCSVData(dataname=datapath, 
    fromdate=dt.datetime(1900, 1, 1),
    todate=dt.datetime(2018, 12, 31),
    plot=False)

or (didn;t use it but should work)

data = bt.feeds.GenericCSVData(dataname=datapath)
data.plotinfo.plot = False

stentor

@ab_trader I tried, but it only disable plotting the original data, not the resampled data.

@ab_trader is telling you how to disable plotting for any data, because you are not showing any code and thus cannot tell where you are doing things wrong

Have you done that for the resampled data instance?

stentor

data = bt.feeds.PandasData(dataname=dt, plot=False)
cerebro.adddata(data=data, name='I000016Min5')
cerebro.resampledata(data, timeframe=bt.TimeFrame.Minutes, compression=1)

I use the above code but I am not sure where to put 'plot=false' for resample data. Your advice is much appreciated! thanks

@ab_trader said in how to disable plotting resample data:

data.plotinfo.plot = False

As indicated by @ab_trader you don't have to put necessarily in the constructor, but if you wish pass it to resampledata as indicated by the documentation

Docs - Cerebro

Or receive the resampled data instance as the result of calling resampledata and do as told by @ab_trader

The above discussion still doesn't clear it for me.
Aim:

To NOT print any resampled data but use it in my strategies.
To print non-resampled data as well as use it in my strategies.

What I have already tried:
Strategy Code

class TestStrategy(Strategy):
    def __init__(self):
        self.close = self.datas[0].close
        self.sma_minutely = SMA(self.dnames.minutely, period=10)

    def next(self):
        pass

Scenario A: plot=False in resampledata function

cerebro = Cerebro(stdstats=False)
data = btfeeds.GenericCSVData(
    timeframe=TimeFrame.Seconds,
    dataname=datapath,
    dtformat=('%Y-%m-%d %H:%M:%S'),
    volume=-1, openinterest=-1
)
cerebro.adddata(data)
cerebro.resampledata(data, name='minutely', timeframe=TimeFrame.Minutes, compression=1, plot=False)
cerebro.addstrategy(TestStrategy)
cerebro.run()
cerebro.plot(volume=False, openinterest=False, style='candle')

Result A:

Traceback (most recent call last):
  File "main.py", line 36, in <module>
    timeframe=TimeFrame.Minutes, compression=1, plot=False)
  File "<masked>/backtrader/cerebro.py", line 839, in resampledata
    dataname.resample(**kwargs)
  File "<masked>/backtrader/feed.py", line 592, in resample
    self.addfilter(Resampler, **kwargs)
  File "<masked>/backtrader/feed.py", line 332, in addfilter
    pobj = p(self, *args, **kwargs)
  File "<masked>/backtrader/metabase.py", line 88, in __call__
    _obj, args, kwargs = cls.doinit(_obj, *args, **kwargs)
  File "<masked>/backtrader/metabase.py", line 78, in doinit
    _obj.__init__(*args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'plot'

Scenario B: plot=False inside GenericCSVData

data = btfeeds.GenericCSVData(
    timeframe=TimeFrame.Seconds,
    dataname=datapath,
    dtformat=('%Y-%m-%d %H:%M:%S'),
    volume=-1, openinterest=-1, plot=False
)

Result B: Plots everything except original data (timeframe=seconds). Not desireable.

Scenario C: Using data.plotinfo.plot=False

data = btfeeds.GenericCSVData(
    timeframe=TimeFrame.Seconds,
    dataname=datapath,
    dtformat=('%Y-%m-%d %H:%M:%S'),
    volume=-1, openinterest=-1
)
cerebro.adddata(data)
cerebro.resampledata(data, name='minutely',
                     timeframe=TimeFrame.Minutes, compression=1)
data.minutely.plotinfo.plot = False
cerebro.addstrategy(TestStrategy)
cerebro.run()
cerebro.plot(volume=False, openinterest=False, style='candle')

Result C:

Traceback (most recent call last):
  File "main.py", line 45, in <module>
    data.minutely.plotinfo.plot = False
  File "<masked>/backtrader/lineseries.py", line 461, in __getattr__
    return getattr(self.lines, name)
AttributeError: 'Lines_LineSeries_DataSeries_OHLC_OHLCDateTime_Abst' object has no attribute 'minutely'

Scenario D: Using data._name with everything else similar to Scenario C

data._minutely.plotinfo.plot = False

Result D:

Traceback (most recent call last):
  File "main.py", line 45, in <module>
    data._minutely.plotinfo.plot = False
  File "<masked>/backtrader/lineseries.py", line 461, in __getattr__
    return getattr(self.lines, name)
AttributeError: 'Lines_LineSeries_DataSeries_OHLC_OHLCDateTime_Abst' object has no attribute '_minutely'

Please guide me to hide plots of resampled data in light of new information above (while allowing me to use it in my strategies).

Cheers

Solved by using data.name.plotinfo.plot = False inside __init__ of strategy

self.dnames.minutely.plotinfo.plot = False

You can try the following:

rdata = cerebro.resampledata(...)
rdata.plotinfo.plot = False
