How to animate text in Matplotlib?
To animate text in matplotlib, we can take the following steps −
- Import "animation" package from matplotlib.
- Set the figure size and adjust the padding between and around the subplots.
- Create a new figure or activate an existing figure.
- Add an 'ax' to the figure as part of a subplot arrangement.
- Initialize a variable "text" to hold a string.
- Add text to the axes at x=0.20 and y=0.50.
- Make a list of colors.
- Make an animation by repeatedly calling a function *animate*, where size of text is increased and color is changed.
- To display the figure, use show() method.
Example
from matplotlib import animation import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = fig.add_subplot(111) text = 'You are welcome!' txt = ax.text(.20, .5, text, fontsize=15) colors = ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf'] def animate(num): txt.set_fontsize(num * 2 + num) txt.set_color(colors[num % len(colors)]) return txt, anim = animation.FuncAnimation(fig, animate, frames=len(text) - 1, blit=True) plt.show()
