Hi there,
I would like to overlay some boxplots onto a time series.
I have tried pylab.hold(True) in between the two plots in my code but this
hasn't worked.
The problem is that the x-axes of the boxplots and the time series are not the
same.
Code for time series:
python2.7
import netCDF4
import matplotlib.pyplot as plt
import numpy as np

plt.legend(loc='best')
plt.xlabel('Year')
plt.ylabel('Significant Wave Height annual averages SW England')
plt.title('Time series of Significant Wave Height')
plt.show()
Code for boxplots:
python2.7
from pylab import *
import netCDF4
data=(hs_Q0_con_sw,hs_Q3_con_sw,hs_Q4_con_sw,hs_Q14_con_sw,hs_Q16_con_sw)
figure(1)
boxplot(data)
labels=('QO no pert','Q3 low sens','Q4 low sens','Q14 high sens','Q16 high
sens')
xticks(range(1,6),labels,rotation=15)
xlabel('Ensemble Member')
ylabel('Significant Wave Height Annual Average')
title('Significant Wave Height SW England 1981-2010')
show()
If anybody knows how I could integrate these two plots I would be eternally
grateful!
Thanks,
Jamie
