python - How can you plot two lists of different 'first dimension' using matplotlib? -

-

i trying write code plots graph whilst going through loop , updates graph each iteration using matplotlib. plotting voltage_trim[0:index] in order avoid problem of having 2 lists of different size still error x , y must have same first dimensions. know how 1 plots 2 lists of different size have updating real time graph? 

voltage_trim = range(16) current_meas = []   fig1 = plt.figure()   index, value in enumerate(voltage_trim):      current_meas.append(random.randint(0,10))      plt.cla()      plt.plot(voltage_trim[:index], current_meas )

your idea of trimming x values good. make work use voltage_trim[:index+1].

the index enumerate starts @ zero, first returned element want select 1 x value. therefore need values index+1.

i'm trying code cyclic autocorrelation function in matlab follows: t=0:(n-1); t=t*te; i_alpha=0; tau=-n2*te:te:n2*te; alpha=-1/2:1/n:1/2; ryy_cl=zeros(length(alpha),length(tau)); alpha=alpha/te ind_tau=0; i_alpha=i_alpha+1; k=tau ind_tau=ind_tau+1; if k>0 % ryy_cl(i_alpha,ind_tau)=1/length(sig_bin_syl_mod(1:end- k))*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(1i*2*pi*alpha*t(1+k:length(sig_bin_syl_mod(1:end)))); ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(-1i*2*pi*alpha*t(1:end-k)); else ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1-k:end)).*sig_bin_syl_mod(1:end+k)).*exp(-1i*2*pi*alpha*t(1-k:end)); end end end i'm getting errors, , doesn't show expecting. according below formulae, how can fix it? the code provided incomplete, difficult confidently reproduce error. in particular, haven't de...
