Please kindly go through following code snippet
for i in range(a1):
data_temp=(bpf[left[0][i]:right[0][i]])# left is an array and right
is also an array
maxloc=data_temp.argmax() #taking indices of max. value of
data segment
maxval=data_temp[maxloc]
minloc=data_temp.argmin()
minval=data_temp[minloc]
maxloc = maxloc-1+left # add offset of present location
minloc = minloc-1+left # add offset of present location
R_index = maxloc
R_t = t[maxloc]
R_amp = array([maxval])
S_amp = minval#%%% Assuming the S-wave is the lowest
#%%% amp in the given window
#S_t = t[minloc]
R_time=array([R_t[0][i]])
plt.plot(R_time,R_amp,'go');
plt.show()
The thing is that I want to plot R_time and R_amp in a single shot.The above
code plots R_time and R_amp each time and overwriting previous value as the
loop continues,i.e. it displays the many graphs each indicating single
point (R_time,R_amp) as long as loop continues.What I want is that all
points from R_time and R_amp should be plotted in one go. I tried to take
array and store the value ,but it takes only one value at the end of loop.
How should I break this loop?Can anybody help me out ????
Thanx in Advance
Regards
Yogesh
