Awesome plotting video... and even more important, really well explained! In this way you grab both the beginner and experienced audience after my opinion.
Brilliant, thank you! I knew that it couldn't be so hard given you can export plots as images, but this is way cleaner than any documentation I attempted to read!
I don't usually comment but this was an excellent tutorial, thanks for making it! Clear and straightforward, I was able to use this on a data visualization problem at work and people love being able to have their own copy of the animation I made.
I've been trying to animate the evolution of a Wigner function as a surface plot for a while now and kept getting stuck but this taught me exactly how to do it! Thank you very much
Quick Question, I've a single "for loop" that generates two outputs. And I like to make two separate mp4's with each one of them. And I only want to run this "for loop" once. how can this be done?
Question. Can this be done in real time? Or does it only collect all data and then render post? Also. This explanation was insanely clear. I never really understood matolotlib until seeing this.
So the rendering itself is done as it goes. Basically what it does is render each frame of the graph and then drops it into a frame buffer. However I believe it does not encode until the end when it saves. From a practical perspective though, for 60 fps it will take longer to run the script than the final video is. If you wanted matching speeds you'd either need to further optimize or set a lower fps for the output I think. I havent timed it, but I believe for most graphs I would do this with, it will take longer than the 8 or 16 ms per frame I'd want to look real time.
@CodingLikeMad I am having trouble to graph values of two parameters generated from python code included loops with multiple if statements. each iteration generate one value of required parameter, and graphing these against the variable responsible of change in values is need! looking for help.
Matplotlib FuncAnimation appears to use global variables. Is there a way to put the FuncAnimation code in a main() function and call it with : if _name_ == "__main__": main()
Hi! I did the same to get the surface levels for a 4D function (f(x,y,z)=x^2+y^2+z^2, here the gif plot a family of spheres of radius R), i wonder if is possible to plot a bar that moves with the variation of R.
I have a function graph(num) where num ranges from 0 to 1000. It returns x and y list for each value of num. Now, I tried running this: with writer.saving(fig, "plot.gif", 100): for num in range(0, 1000+1): x, y = graph(num) l.set_data(x, y) writer.grab_frame() But it throws me the error: list index out of range. Could you help me with this, why do I have this error?
Very nice video, thank you! I have some data files that have information such as coordinates and vector components in a mesh in a plane. These data files show evolutions of vectors (dipoles) over Monte Carlo steps. I can plot each step of course as density plot in a seaborn but it would be nice to visualize how the dipoles evolve over Monte Carlo steps. Do you have any suggestions where I need to begin? Thank you again
Thanks for the video. I am only seeing a plot of the wave with no animation. Would you know why that is? Below is my code. import matplotlib.pyplot as plt import numpy as np from matplotlib.animation import PillowWriter fig = plt.figure() l,= plt.plot([], [], 'k-') plt.xlim(-5, 5) plt.ylim(-5, 5) def func(x): return np.sin(x) metadata = dict(title='Movie', artist='test') writer = PillowWriter(fps=15, metadata=metadata) xlist = [] ylist = [] with writer.saving(fig, "sinWave.gif", 100): for xval in np.linspace(-5,5,100): xlist.append(xval) ylist.append(func(xval))
Thank you so much, this was really helpful! I've been trying to display also the frame number on the plot (in the .gif file) but I can't really figure out how to do it. Any ideas?
I want to learn sir please tell me the process, I want to see mathematical equation and theorem, moving and visualization like a pro.... What to learn first and where ?
Hey, thank you for the tutorial, anyone has an idea why PyCharm might be returning a blank frame (no values/grid no nothing) .gif file? so seems it's not even generating a first frame. Generating a static Fig. works without any problems. thank you in advance
For this tutorial I had increased the font size in pycharm to make things more visible, I'll look into improving viewability more. Thanks for the feedback :)
I never comment on YT, but I have to say, you have an exceptional talent for teaching. Thank you for this clear explanation !
Thankyou :)
Best tuto ever on this topic where others are so complicated !
Thanks so much :)
Showing how to solve the error by defining the path to ffmpeg was very helpful! Thanks a lot. :)
Awesome plotting video... and even more important, really well explained! In this way you grab both the beginner and experienced audience after my opinion.
The best tutorial about animated graphs I've ever seen!
Definitely going to be using this as the basis to animate/plot some MLB pitches. Thanks for the tutorial!
You taught me a whole new way to think about data visualization animation. Fantastic vid! Thanks!

I like to use ffmpeg and ffplay when testing cameras used for OpenCV. Nice job ! Keep it up.
Your 3D surface plot animation in the github was saved my day. Thank you.

Thank you for the tutorial. You have a really good teaching style, clear and easy to follow.
Thank you for the very useful video, it was easy to understand
Nice and clear, just what I needed ! Thank you very much !
It doesn`t work in Jupyter Notebook
This is fantastic. Thank you sir! I'll use it on my projects :)

First, excellent tutorial, thank you. Question: How would you add an audio track to the generated .mp4?
Then there's no point of buying Tableau or Power BI for data visualization; you truly are a genius.
@CodingLikeMad
I am having trouble to graph values of two parameters generated from python code included loops with multiple if statements. each iteration generate one value of required parameter, and graphing these against the variable responsible of change in values is need! looking for help.
How to display one point at a time, i.e point by point without keeping the past plots? So that it can display as a single moving dot?
Thanks man, this was super helpful.
Thank you for the excellent video content. I would suggest that you use a larger font and one with greater contrast.
Could this be done within the Python visualization of Power Bi? I’ve been trying to use Plotly for this but that library isn’t supported.
Wow that was so wonderfully made! Loved it!

thank you! very nice explanation
Hello, is it possible to feed live data to the program and plot it with your method sir?
Thank you.
With sufficient work, yes. But itd be pretty round about I think.
Excellent useful and clear video, I'm recommending your channel!
Appreciate it, glad you liked it.
I have a function graph(num) where num ranges from 0 to 1000. It returns x and y list for each value of num.
Now, I tried running this:
with writer.saving(fig, "plot.gif", 100):
for num in range(0, 1000+1):
x, y = graph(num)
l.set_data(x, y)
writer.grab_frame()
But it throws me the error: list index out of range.
Could you help me with this, why do I have this error?
Which line throws that error? If it is l.set I'd guess your x and y are not the same length. I'd check the content of x and y first.
loved it thank you
What if you have an xcel sheet with x and y values you want to animate with gif?
Export it to a csv, then load it from python using something like readcsv()

Great video! Thanks
I have a question : what if we want to create a video from matrixes that we convert into images ? Is it the same idea ?
As long as the matrix display is done through matplotlib, it should be the same, yep. I havnt tested it, but I assume it will work for you.
You could have just used the linspace as xlist and ran np.sin(xlist) that would have given you the vectorized versions of xlist and ylist.
Thank you so much, this was really helpful! I've been trying to display also the frame number on the plot (in the .gif file) but I can't really figure out how to do it. Any ideas?
Great video 👏👏👏 subbed
Thank you for this. I learned so much 😊
hi sir this video is great
but when i try to do this i got an error in google colab as "List index out of range " can you help me how to solve that
Can you say where the error occurs?
simplest=most_powerful
Sometimes it to be that way :)
you deserve more subscribers ☺ ☺ ☺ ☺ 👏 👏 👏 👏
I want to learn sir please tell me the process,
I want to see mathematical equation and theorem, moving and visualization like a pro....
What to learn first and where ?
great video!
Truly outstanding tutorial! Thank you.

Amazing
As simple as that. Nice explanation.
Question, Mad... Is your full name Madison?
very helpful video. thanks!
thank you bro! just what I want to learn right now :D
Thank you for the wonderful video!
This was awesome but when is the next Mistborn book coming out?
Thank you very much for the instructions
Very neat!! Thanks!!
Great job. Thanks a lot.
Many many thanks..... Please carry on❣️
Codes are literally 2px on my phone lol
Yeah, I'd recomend not looking at code on your phone :p
nice matplotlib 🙂
Wish u were my teacher :]
Thanks for your tutorial. But, please, zoom your screen.
