How to add a variable to Python plt.title?
You can use print formatting.
plt.title('f model: T= {}'.format(t))
orplt.title('f model: T= %d' % (t))
# c style print
You can change a value in a string by using %
. Documentation can be found here.
For example:
num = 2
print "1 + 1 = %i" % num # i represents an integer
This will output:
1 + 1 = 2
You can also do this with floats and you can choose how many decimal place it will print:
num = 2.000
print "1.000 + 1.000 = %1.3f" % num # f represents a float
gives:
1.000 + 1.000 = 2.000
Using this in your example to update t
in the figure title:
plt.figure(1)
plt.ylabel('y')
plt.xlabel('x')
for t in xrange(50,61):
plt.title('f model: T=%i' %t)
for i in xrange(4,10):
plt.plot(1.0/i,i**2,'ro')
plt.legend
plt.show()
