Is there a way to hide this from the input window?
len = input(5, minval=1, title="EMA_1")
src = input(close, title="Source")
out = ema(src, len)
plot(out, color=red,linewidth=1, title="EMA_1", transp=0)
len1 = input(20, minval=1, title="EMA_2")
src1 = input(close, title="Source")
out1 = ema(src1, len1)
plot(out1, color=green, title="EMA_2", transp=0)
