I am trying to create a figure in python and make is so that the same annonate text will have two colors, half of the annonate will be blue and the other half will be red.
I think the code explain itself. I have 3 lines 1 green with green annonate, 1 blue with blue annonate.
The 3rd is red its the summation of plot 1 and plot 2, and I want it to have half annonate blue and half green.
ipython -pylab
x=arange(0,4,0.1)
exp1 = e**(-x/5)
exp2 = e**(-x/1)
exp3 = e**(-x/5) +e**(-x/1)
figure()
plot(x,exp1)
plot(x,exp2)
plot(x,exp1+exp2)
title('Exponential Decay')
annotate(r'$e^{-x/5}$', xy=(x[10], exp1[10]), xytext=(-20,-35),
textcoords='offset points', ha='center', va='bottom',color='blue',
bbox=dict(boxstyle='round,pad=0.2', fc='yellow', alpha=0.3),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=0.95',
color='b'))
annotate(r'$e^{-x/1}$', xy=(x[10], exp2[10]), xytext=(-5,20),
textcoords='offset points', ha='center', va='bottom',color='green',
bbox=dict(boxstyle='round,pad=0.2', fc='yellow', alpha=0.3),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=-0.5',
color='g'))
annotate(r'$e^{-x/5} + e^{-x/1}$', xy=(x[10], exp2[10]+exp1[10]), xytext=(40,20),
textcoords='offset points', ha='center', va='bottom',
bbox=dict(boxstyle='round,pad=0.2', fc='yellow', alpha=0.3),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=-0.5',
color='red'))
Is it possible?
You can use r'$\textcolor{blue}{e^{-x/5}} + \textcolor{green}{e^{-x/1}}$'
to make the text half blue, half green. Using your own code for example:
The image is generated by the following code. Testd with matplotlib v2.1.2 with the default matplotlibrc
settings.
import matplotlib as matplotlib
matplotlib.use('pgf')
matplotlib.rc('pgf', texsystem='pdflatex') # from running latex -v
preamble = matplotlib.rcParams.setdefault('pgf.preamble', [])
preamble.append(r'\usepackage{color}')
from numpy import *
from matplotlib.pyplot import *
x=arange(0,4,0.1)
exp1 = e**(-x/5)
exp2 = e**(-x/1)
exp3 = e**(-x/5) +e**(-x/1)
figure()
plot(x,exp1)
plot(x,exp2)
plot(x,exp1+exp2)
title('Exponential Decay')
annotate(r'$e^{-x/5}$', xy=(x[10], exp1[10]), xytext=(-20,-25),
textcoords='offset points', ha='center', va='bottom',color='blue',
bbox=dict(boxstyle='round,pad=0.2', fc='yellow', alpha=0.3),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=0.95',
color='b'))
annotate(r'$e^{-x/1}$', xy=(x[10], exp2[10]), xytext=(25,20),
textcoords='offset points', ha='center', va='bottom',color='green',
bbox=dict(boxstyle='round,pad=0.2', fc='yellow', alpha=0.3),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=-0.5',
color='g'))
annotate(r'$\textcolor{blue}{e^{-x/5}} + \textcolor[rgb]{0.0, 0.5, 0.0}{e^{-x/1}}$',
xy=(x[10], exp2[10]+exp1[10]), xytext=(40,20),
textcoords='offset points', ha='center', va='bottom',
bbox=dict(boxstyle='round,pad=0.2', fc='yellow', alpha=0.3),
arrowprops=dict(arrowstyle='->', connectionstyle='arc3,rad=-0.5',
color='red'))
savefig('test.png')
It is mainly your code with the following changes:
pgf
backend.color
in pgf.preamble
xytext
is changed.color='g'
in te 2nd annotation actually didn't use the pure "Green" color like (0, 255, 0) of rgb. \textcolor[rgb]{0.0, 0.5, 0.0}
makes it looking alike.
