i add global title group of subplots using plots.jl. ideally, i'd like: using plots pyplot() plot(rand(10,2), plot_title="main title", title=["a" "b"], layout=2) but, per plots.jl documentation , plot_title attribute not yet implemented: title whole plot (not subplots) (note: not implemented) in meanwhile, there way around it? i'm using pyplot backend, i'm not tied it. when using pyplot backend, can use pyplot commands alter plots figure, cf. accessing backend specific functionality julia plots . to set title whole figure, like: using plots p1 = plot(sin, title = "sin") p2 = plot(cos, title = "cos") p = plot(p1, p2, top_margin=1cm) import pyplot pyplot.suptitle("trigonometric functions") pyplot.savefig("suptile_test.png") one needs explicitly call pyplot.savefig see effect of pyplot functions. note changes made using pyplot interface overwritten when use plots

i check if argument argsparse chosen, if not choose random value variable. here example: parser.add_argument('--tempo', default=120, type=int, help='tempo of track') and 1 way example: args = parser.parse_args() if args.tempo==120: #my default int tempo=random.randint(60,350) but way when user call program example: main.py --tempo 120 , choose random value. how can check if argument chosen or not? the problem in test. if user chose 120 give random number. think best remove default , check if empty. parser.add_argument('--tempo', default=none, type=int, help='tempo of track') args = parser.parse_args() if args.tempo==none: #my default int args.tempo=randint(60,350)
