I am a beginner in zeppelin.
I would like to plot a dynamic plot which can auto update the graph when the new data is added.
I tried to import matplotlib.animation in zeppelin, it didn't work.
But it can work in Spyder and jupyter.
Does anyone can help me please?

I know this may sound like a nooby question but I am new to python and am trying to graph some stock data using pandas. I know this is not technically a programming question but do I need to install anything special for the graph to print or does it just graph in the IDE console? Or none of the above? Thanks in advance
Welcome to the world of python programming!
To graph using Matplotlib, first you would have to ensure it is installed in your system:
pip install matplotlib
And then import it into your code using
import matplotlib.pyplot as plt #import the plotting method in Matplotlib
Following this import and creating your plot, you can have your plot shown using
plt.show()
The plots are not displayed inline in notebooks when using matplotlib
The plots appear completely blank. Any ideas?
Came across the same issue on calling "Restart & Run all". Following this
%matplotlib notebook showing a blank histogram
I could resolve the issue adding
%matplotlib inline
at the beginning of the cell. Also note that you can prevent string output by adding ; to the end of a line.
I faced a similar issue with my Chrome Browser, whereas it works fine with Mozilla.
%matplotlib inline will lead to static images of your plot embedded in the notebook, so that cannot be the solution for this prevailing issue.
If you're trying to create a graph using the Object-Oriented Interface try adding
fig, ax = plt.subplots()
above your ax.plot
Had a similar issue - %matplotlib notebook command would not display the plot but %matplotlib inline would. Had to downgrade matplotlib version from 3.1.3 to 3.1.2.
Python 3.7.9, conda 4.5.11
While importing and attempting the following:
import matplotlib
from matplotlib import pyplot as plt
plt.plot([1,2,3],[1,4,9])
plt.show()
I get the following error. How do I fix? I am running Python 2.7, and notebook version 4.1.0. Thank you.
RuntimeError: Invalid DISPLAY variable
When running a jupyter notebook on a server, the server may not even be able to display the plot. The usual solution would be to use a non-interactive backend. In case of a jupyter notebook this would be done by adding
%matplotlib inline
at the top of the notebook, such that graphics are shown as png images.
Quite new to python and programming and tried to search for answers to matplotlib plots, but couldn't find answers to my question.
I use Spyder and have anaconda installed. Installed matplotlib but when i run simple plot commands I just get <"matplotlib.figure.Figure at 0x11090c18"> and no plot
If I run it in a dedicated python interpreter i just get an empty plot
The simple code is:
from matplotlib import pyplot as plt
plt.plot([1,2,3,4,5], [2,4,6,8,10])
plt.show()
Is this just the result of some stupid error I made in the installation process?
Hope someone can help med out
I think the error you're seeing is generated by a change the Matplotlib team did some months ago. I tried to fix it in Spyder 2.3.0/1 but maybe it's not working correctly.
To see a plot the code you need to run is
from matplotlib import pyplot as plt
plt.ion()
plt.plot([1,2,3,4,5], [2,4,6,8,10])
plt.show()
Notice the second line, that's what's needed to get interactive plots.
I am working with python networkx and matplotlib.pyplot.
The code I am using is the following:
import networkx as net
import matplotlib.pyplot as plot
orgchart = net.read_pajek("ACME_orgchart.net")
net.draw(orgchart)
The code does not throw errors and runs fine but the graph that is supposed to appear, does not and I know the code runs fine because an icon appears in the dock which I am sure signifies the graph visualization software in python but the actual visualization does not appear . This code is from the book "Social network analysis for startups" if someone could please help me figure this problem out I would be really grateful.
I am using python 2.7.3, on mac osX, with networkx, matplotlib, numpy installed.
The problem was that my matplotlib was not being used in interactive mode. Hence when working with an interactive display I needed to also include the line: plot.show() at the end for the display to appear.
