plot size question

Alain

Hi!
When I make a plot as in the following:

num = 20
fig = cerebro.plot(numfigs = num, barupfill = False, bardownfill = False, style = 'candle', plotdist = 0.5, 
                   figsize=(30,30), volume = False, barup = 'green', valuetags = False, subtxtsize = 7,
                   start = startdate, end = enddate)

for i in range(num):
    fig[0][i].tight_layout()
    fig[0][i].savefig(output_folder + '/{}_'.format(timeframe) + stratname + '_{}'.format(strat_type) + '_plot{}.png'.format(i), dpi=300, hight = 30, width = 30, tight = True)

I get one very nice big plot as can be seen here (it's the second image printed):

and 19 small not so nice plots (where one can be seen here):

What could be the reason ? Would love to see 20 plots similar to the first one.

Thank you for your help!

figsize=(30,30)

Hey @Alain, I was wondering how you got the plot to change size at all!? Which IDE are you using?

Best,

hight = 30

Things are in the matplotlib arena, but that could have something to do with it.

Hi @nikitaj and @backtrader

Actually the figsize = (30,30) command didn't do anything to the plots. I also deleted hight = 30, but nothing changed...
I'm using anaconda -> spyder.

The code now looks like this

fig = cerebro.plot(numfigs = num,barupfill = False, bardownfill = False, style = 'candle', plotdist = 0.5, 
                   volume = False, barup = 'green', valuetags = False, subtxtsize = 7,
                   start = startdate, end = enddate)

for i in range(num):
    fig[0][i].tight_layout()
    fig[0][i].savefig(output_folder + '/{}_'.format(timeframe) + stratname + '_{}'.format(strat_type) + '_plot{}.png'.format(i), dpi=500)

and unfortunately I still get one nice plot and all others are small... no idea why.
Should all plots look like the big one I posted ?

Thanks,
Alain

Do it in the shell.

same result unfortunately... also updated matplotlib, de- and reinstalled anconda, but nothing helps so far.

I have the same problem but when I remove bt.ind.StdDev from the strategy the fig size becomes okay.
