How do I display the full output that includes graphics?

Background

I am working in the notebook GUI.

I have code that produces graphics (.png files) to display arrays with colors satisfying certain combinatorial criteria. When the output gets too long, Sage returns the message

WARNING: Output truncated!
full_output.txt

The .txt file contains some html code, but doesn't display in a web browser.

Question

How do I see my graphical arrays?

It would be very helpful to have a minimal case that produces this. You can get it by having a loop like "for i in range(100000): print factorial(i)" but I haven't seen it in this context.

By the way, wrapping the .txt file in standard HTML headers and <body> etc. then renaming that to html *might* work... just a random chance.

Try writing your output to an html file. Do something like:

f=open('myoutput.html','w')
f.write(some output)
f.write(some more output)
f.close()

That file should appear as a link in the output of the cell. If you click on the link, you should see your output as an html file.

This could be helpful to have on the standard notebook help page as an FAQ or something.

I found this solves the problem: put this line in your notebook cell before you create output.

html('<!--notruncate-->')

Worked for me.

This is very helpful! It can also be inserted in the definition of a function. A 2009 suggestion on the sage-support list was to change values of variables in the file devel/sage/sage/server/notebook/cell.py and rebuild SAGE, which isn't feasible in many cases, such as when using SAGE in a classroom where it's been installed on multiple machines. Since there are pedagogical scenarios where we'd like all of the output to display, may I suggest that this solution be mentioned in the SAGE reference manual? (Searching for "notruncate" in version 6.4.1 of the manual produces three hits, none quite containing this solution.)
