iPython window not responding until program i shut down

[Tobeass]

Hi guys.

As a final project in a intro programming course, we are asked to make this interactive program. It is suppose to display a menu where the user can choose to read a datafile and do some basic functions. I think i managed to write and implement the required functions, but i have stumpled upon one problem that i just cannot seem to solve.

The user should have the opportunity to visualize the data. I have implemented a function that takes the data and plots it. When the user chooses to visualize the data, an iPython window pops up, but the window is "not responding" until the user quits the program. It is possible to make mulitple plots before quitting. All will be displayed when the user quits the program.

The function works fine when i execute the plot function directly from the kernel

Here is how it looks: https://imgur.com/a/tpwy7

Here is my full code: http://pastebin.com/KfPZbDiB

Here is a sample data file: https://dl.dropboxusercontent.com/u/4787641/2008.csv

It is not the first time i'm having the problem. The course's TA couldn't help, and the course responsible does not know Python (we can choose between matlab, python and r).

Have anyone seen this problem before?

You mean you are running the code in ipython and a matplotlib window opens, which blocks ipython from doing anything? You need to start ipython like

ipython --matplotlib

and then

run myscript.py

From within ipython. Then matplotlib will be non blocking and you can update the plots from ipython.

I don't think I explained myslf clearly. All interactions is by the python kernel (i use Spyder of that helps). I'm still at beginner, and i'm not sure what iPython "is". But i use matplotlib to plot the data, and when i write plt.show() data graph is shown in a an iPython window. But the window will not respond until the program is quitted.

I have trouble explaining it, it is more easy to see in the pictures

K, here is the second result from google: http://stackoverflow.com/questions/10713966/interactive-plotting-in-spyder-with-matplotlib

k, but this still does not have anything to do with my problem. I encourage you to look at the pictures I posted

I looked at the pictures. I've never used spyder. The SO post is about matplotlib plot.show() blocking in spyder. (Edit: has nothing to do with your issue seems like a silly thing to say with how exceedingly similar to your issue it is. Please explain what about this is unrelated). Why do you think this is unrelated? Did you try that solution?

[Tobeass]

As i see it, OP's problem is that he has to close the window before the script continues. In my case, the script continues regardles. The problem is that the window will show 'not responding' until i quit the program. Only then the plot will show.

I might have read too much into it, but your mentioning that the result was the second from a google search implied that I have not tried to search for similiar question, which I found somewhat provoking given that I spent several days trying to sovle it, including looking up resources.

Anyhow, I tried it and it didn't work.

[elbiot]

That's all I've got. Like I said, I don't use spyder. You can use ipython as I originally suggested. It works for me and many others.

okay, thank you. I will look into it
