Here we use a function animate () that changes the coordinates of a point on the graph of a sine function. The notebook with all the code is here (rendered on Github). This example operates by precomputingthe pendulum position over 10 seconds, and then animating the results. Examples Basic animation with FuncAnimation The matplotlib.animation package offer some classes for creating animations. So, what you can do instead is to use a higher level package like seaborn, and use one of its prebuilt functions to draw the plot. One thing to know is that a coil is nothing but a composite function of sine and cos. We take the sine function in x-axis and cos in y-axis and the resultant figure gives a coil. The following are 30 code examples for showing how to use matplotlib.animation.FuncAnimation().These examples are extracted from open source projects. But this time, we import the matplotlib.animation library completely, however, in the previous example, we imported just the FuncAnimation function from it. In this tutorial we are going to take a look how to create a basic animation using matplotlib in Python. Matplotlib is a Sponsored Project of NumFOCUS, a 501(c)(3) nonprofit charity in the United States. For example, in matplotlib, there is no direct method to draw a density plot of a scatterplot with line of best fit. As already said, we will be using the function method as opposed to the artistic objects. Here we will try and make a continuous sine wave using animations and plotting tools. The hardest thing about creating animations in matplotlib is coming up with the idea for them. It uses Matplotlib’s Axes3D . Saving can be in video or .gif format. animation example code: movie_demo.py ... script demonstrates how to use the numarray package # to generate and handle large arrays of data and how to use the # matplotlib package to generate plots from the data and then save # those plots as images.

Example #. Next we initialize a variable line which will contain the x and y co-ordinates of the plot. Let’s check an example. Basic animation with FuncAnimation. Finally, we state the animation function animate(i) which takes an argument i, where i is called the frame number and using this we create the sine wave(or any other figure) which will continuously vary depending upon the value of i. In the last line anim = FuncAnimation(fig, animate, init_func=init, frames=200, interval=20, blit=True) we use the FuncAnimation function to create an animation which will display 200 frames per second and in an interval of 20 micro secs. Try to guess the output as we code the program as it will clear our concept.
