I am able to put titles on the subplots using Sage's plotting function, but unable to put titles on the subplots using matplotlib. Here is a simplified code of what I am working with:
import matplotlib.pyplot as mpl
#Function defining Legendre Functions of the Second Kind using Bonnet's recursion formula:
def legendre_second(n,x):
if (n ==0):
return log((x+1)/(x-1))/2
elif (n==1):
return x*legendre_second(0,x) - 1
elif (n>1):
return ((2*n-1)*x*legendre_second(n-1,x) - (n-1)*legendre_second(n-2,x))/n
#Creating a plot list for the first four legendre function of the second kind:
l = []
p = plot(legendre_second(0,x), (x, 1,10), title = r'$Q_0$')
l.append(p)
p = plot(legendre_second(1,x), (x, 1,10), title = r'$Q_1$')
l.append(p)
p = plot(legendre_second(2,x), (x, 1,10), title = r'$Q_2$')
l.append(p)
p = plot(legendre_second(3,x), (x, 1,10), title = r'$Q_3$')
l.append(p)
Plotting Using Sage
# Label the plots on the left column
for i in range(0,2,2):
l[i].axes_labels(["","Value"])
# Label the plots in the last row
l[-2].axes_labels(["x interval ","Value"])
l[-1].axes_labels(["x interval ",""])
gpairs = list(zip(l[::2], l[1::2]))
pic=graphics_array(gpairs)
graphics_array(gpairs).show(frame=True,figsize=[9,7],gridlines=True)
In which I obtain subplots with titles, I would upload picture but it says I need >60 points to upload files
Now on to plotting with matplotlib
fig = mpl.figure(figsize = (15,10))
for i, g in zip(range(1, 5), pic._glist):
subplot = mpl.subplot(2, 2, i)
g.matplotlib(figure=fig, sub=subplot, verify=True, axes=True, frame=True, gridlines='major')
With matplotlib I am able to obtain the subplots with the x and y axis labels, but the titles of each subplot do not transfer over to the figure created by matplotlib. How do I create titles for each individual subplot in matplotlib? Is it also possible to create an overall title for the entire figure? Thanks again for all of your guy's/girl's help. @dsejas
