How to Increase Plt. Title Font Size?
I'm Using Pythons Matplotlib and This Is My Code: Plt. Title('Temperature \N Humidity') How Can I Just Increase the Font Size of Temperature Instead of Both...
I'm using Pythons matplotlib and this is my code:
plt.title('Temperature \n Humidity')
How can I just increase the font size of temperature instead of both the temperature & the humdity?
This does NOT work:
plt.title('Temperature \n Humidity', fontsize=100)

fontsize can be assigned inside dictionary fontdict which provides additional parameters fontweight, verticalalignment , horizontalalignment
The below snippet should work
plt.title('Temperature \n Humidity', fontdict = {'fontsize' : 100})
import matplotlib.pyplot as plt
plt.figtext(.5,.9,'Temperature', fontsize=100, ha='center')
plt.figtext(.5,.8,'Humidity',fontsize=30,ha='center')
plt.show()
Probably you want this. You can easily tweak the fontsize of both and adjust there placing by changing the first two figtext positional parameters.
ha is for horizontal alignment
Alternatively,
import matplotlib.pyplot as plt
fig = plt.figure() # Creates a new figure
fig.suptitle('Temperature', fontsize=50) # Add the text/suptitle to figure
ax = fig.add_subplot(111) # add a subplot to the new figure, 111 means "1x1 grid, first subplot"
fig.subplots_adjust(top=0.80) # adjust the placing of subplot, adjust top, bottom, left and right spacing
ax.set_title('Humidity',fontsize= 30) # title of plot
ax.set_xlabel('xlabel',fontsize = 20) #xlabel
ax.set_ylabel('ylabel', fontsize = 20)#ylabel
x = [0,1,2,5,6,7,4,4,7,8]
y = [2,4,6,4,6,7,5,4,5,7]
ax.plot(x,y,'-o') #plotting the data with marker '-o'
ax.axis([0, 10, 0, 10]) #specifying plot axes lengths
plt.show()

This has been mostly working for me across recent versions of Matplotlib (currently 2.0.2). It is helpful for generating presentation graphics:
def plt_resize_text(labelsize, titlesize):
ax = plt.subplot()
for ticklabel in (ax.get_xticklabels()):
ticklabel.set_fontsize(labelsize)
for ticklabel in (ax.get_yticklabels()):
ticklabel.set_fontsize(labelsize)
ax.xaxis.get_label().set_fontsize(labelsize)
ax.yaxis.get_label().set_fontsize(labelsize)
ax.title.set_fontsize(titlesize)
The odd for-loop construction seems to be necessary to adjust the size of each tic label.
Also, the above function should be called just before the call to plt.show(block=True), otherwise for whatever reason the title size occasionally remains unchanged.
Assuming you are using matplotlib to render some plots.

Here are some lines of code for your case
plt.rc('text', usetex=True)
plt.title(r"\begin{center} {\Large Temperature} \par {\large Humidity} \end{center}")
Hope that helps.
Simply do the following:
ax.set_title('This is the title',fontsize=20)
I don't want to go into this chart exactly Universal method: step one - make a distance between the main title and the chart:
from matplotlib import rcParams
rcParams['axes.titlepad'] = 20
then insert subtitle by setting coordinates:
ax.text(0.3, -0.56, 'subtitle',fontsize=12)
