Would anyone know how to recreate this flow chart in networkx? I know I can manually add these nodes and add the edges, but I wanted to write some code that could be applicable for other data types like CSV or EXCEl.
My main idea was to convert this flow into Excel and then have the program read that file and create nodes and edge.
I do have something that is able to read the file and then create nodes using that file. However, I cannot get the edges and the specificities of the flow correct in network.
If anyone could help that would be great. Thanks
This is the flow I wish to recreate
I would try loading the csv into a pandas dataframe. Networkx can be very finicky on how the incoming data needs to be formatted. So I would import it to the dataframe the have networkx read it out of there.

I have a pandas dataframe that contains 3 columns , ['source' , 'target', 'weight'].
I have created a networkx graph successfully and plotted it in the browser. The networkx graph was created using the following line of code:
Graph = nx.from_pandas_edgelist(rules,source='source',target='target').
Using the networkx library, it was easy to create the graph using only the above line of code, and setting the nodes labels, arrows that shows the sense from source to destination etc...
I want to do this using plotly dash to have an interactive plot, however, in the examples I have seen in plotly dash networkx, they always have to declare the nodes and edges manually, which will require to have a for loop over the dataframe to pass all the entries of the dataframe. In my case, I have a pretty large dataframe which will be a problem.
My question is that, is there a way that I am missing, to create the graph using dash in a simple way without the need to declare the edges and the nodes manually? a way similar to that line of code?
Graph = nx.from_pandas_edgelist(rules,source='source',target='target').
and if there is a way, can I access the nodes by their ids? and how to insert nodes labels in the graph.
Thank you in advance.
I have tries visdcc and cytoscape libraries using plotly dash. In visdcc I used a loop which took a lot of time to pass through the dataframe entries. And in cytoscape, it needs to create the nodes and edges manually, which I do not want to do, my question is, if there is a way to create the graph automatically using the dataframe as networkx and the draw option do.
Yes, it is possible to use a dataframe to create a network graph with Networkx and then render this network graph in Dash-Cytoscape (you don't have to enter nodes and edges manually). In the question I asked yesterday (here), you can find a code example to achieve this (my question was about something more specific).
I am using Python module pyvis to plot a network graph. Like manytimes, the initial graph is cluttered for the nodes, so i do the node moves to make it clean and better. After that i save the HTML file. When i reopen the HTML file again, the node positions which i changed for a better and clean look is reset and back to same random plotting.
Is there a way i can lock the network plot after improving the node layout and positions ? is there a way we can force the java script to save also the node/edge locations,colors,lengths and reuse on next open of the graph?
Where is the information about node positions stored for HTML graph? is it something computed dynamically during the java script run when HTML file is opened?
From the docs, you can look at this small gif:
[animated gif](https://pyvis.readthedocs.io/en/latest/_images/set_options_ex.gif)
Basically:
Once you have configured all the parameters in your graph trough the buttons:
g.show_buttons()
You can copy & paste those options inside 'set_options':
g.set_options("""
pasted_options_copied_from_generate_options_button
""")
And before run it again, comment the 'show_buttons()':
# g.show_buttons()
I have downloaded json dump of webRTC from chrome://webrtc-internals/. Now I want to analyze the logs and need to plot graphs. In the stats there are multiple fields which I don't understand. Can someone explain what these fields stand for and how can I use them to plot video quality and bitrate vs timestamp graph.
You can look at https://fippo.github.io/webrtc-dump-importer/ which I wrote to import the dump and plot graphs. The format exported by webrtc-internals is not specified and change at any time but the javascript implementation has worked for a couple of years now.
Plotting video quality largely depends on how you define that. The dump gives you just a lot of numbers.
How to extract data from plot data filter in paraview through python script?? I want to get data through python script by which paraview is drawing the graph.
If anyone know this answer please help
Thank you
Usually plots are made by plotting one data array versus another. You can often obtain that data directly from the filter/source that produced it and save it to a CSV file. To do this, select
You can save data from a filter as a CSV file by selecting the filter/source in the Pipeline Browser and choosing File -> Save Data. Choose the CSV File (*.csv) file type. Arrays in the filter/source output are written to different columns in the CSV file.
I have got graph which need to analyzed and report an Error.As of Now I had a data in Excel data.So I have used xlsxwriter to Create graph.But I need to analyze graph.
1.Solid red line was created using xlsxwriter using excel data and was very easy to implement.
In later Enhancement,
2.In Ideal condition,The formula provided to us, we will have dotted red line. So we need to determine difference and report an error.
So First approach was, write a data in Excel sheet using formula and compare data into Excel sheet and report an error.
But we also need to represent into graph also and we will have upcoming task also in which we require graph (basically 2D and line graph) I have googled and found matplotlib which generally use for create graph. So I have very basic question,
Can anyone suggest me library which can be used for this scenario. it will be great if I have input any standard graph library(cover Line grpah) So I can put effort to familiarize with them. it will save lot of effort of us. we generally create graph for circuit analysis.
Language : Python
Environment : Linux
Library : Should be open source
I know, it is very open ended question.But I thought Let have a opinion who has used graph in Python
or is it possible to create below like diagram using matplotlib
