With a strategy with multiple instruments, anyway to make one plot per?

[CptanPanic]

I have multiple instruments with corresponding data feeds. The resultant plot() is way too busy, and would like to have a plot() for each instrument, even if that meant that the top portfolio section is the same between plots. Can this be done?

Thanks.

No and yes. Plots are strategy-based and not data-based.

But you could selectively disable which data feeds have to be shown and then replot. This is completely untested, but it should be something like this:

st = cerebro.run(....)[0]  # assume only interest in 1st strategy (probably the only one)

for i in range(len(st.datas)):
    for j, d in enumerate(st.datas):
        d.plotinfo.plot = i == j
        
    cerebro.plot()

Thanks,
That does work. Alternatively is there a way to get access to this raw data so I can plot myself?

Each line in a data feed has:

• An attribute array which holds the data
• Method getzero(idx, size) to return the data from the beginning
• Method plot(idx=0, size=None) which if called as plot() will simply give you the entire array
