Histogram not shown

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Checkout current version from svn
2. Run code_swarm on code_swarm repository

What is the expected output? What do you see instead?
Although the histogram has been enabled in the configuration file
(ShowHistory=true) the histogram is not drawn.

What version of the product are you using? On what operating system?
Checkout from today on Fedora 10.

Please provide any additional information below.
I have added some debug output. The drawHistory() routine is executed, but
nothing shows up. There is a lot of activity, but no histogram.

I can't reproduce this bug and this is the first time anyone has had trouble 
with the 
histogram. Is it possible that, since code_swarm is a small project, the 
histogram is 
being drawn with very small levels?

Is OpenGL enabled?  I ran into this bug myself and fixed it with these patches:

For whatever reason the OpenGL renderer won't draw lines.  For the simple 
vertical case we can get around this 
by drawing thin rectangles.

I also noticed that I could not get the histogram to work at the same time that 
I was 
drawing edges.

Looking at the code it seems that the edge.draw changes the strokeWeight but 
does not 
set it back the the default.

The unset strokeWeight after edge drawing appeared to be the problem. Thanks!
