Upgrade lost Graphs

[potter]

I am in the process or upgrading and moving my Trac installation.  Moving from Windows, Python 2.5, Trac 0.12.2, Bitten 0.6b3 to Ubuntu, Python 2.7, Trac 1.0.1, Bitten 0.6.  So far everything is looking fine except for when I go to a Build Configuration page (e.g. http://host/trac/build/buildConfig) the graphs are missing.  The header for the graphs are there, and space where the graphs would appears but not even a bounding box.  

What might I be missing of what might I have done wrong?

If I go to http://host/trac/build/buildConfig/chart/test or http://host/trac/build/buildConfig/chart/lint on the old or the new host I get the same collection of data be be graphed.  If I examine the HTML on the new host where the chart's should be is an empty div:

<div id="chart_lint" style="height: 220px; width: 310px;"></div>

However on the old host the div has some canvas's and div's with all the data. 

<div id="chart_lint" style="height: 220px; width: 310px; position: relative;">

<canvas width="310" height="220">

</canvas>

<canvas width="310" height="220" style="position: absolute; left: 0px; top: 0px;">

</canvas>

<div class="tickLabels" style="font-size:smaller;color:#545454">

    ...

</div>

<div class="legend">

    ...

</div>

</div>

"Or" that is, as in "What might I be missing or what might I have done wrong?"

Hello

It looks like the Javascript that renders the charts isn't running. Do
you see any errors in the Javascript console?

Sure enough:

Failed to load resource: the server responded with a status of 404 (Not Found)

http://host/trac/chrome/bitten/excanvas.js

Went looking for excanvas.js and jquery.flot.js.  Found them on the old host inside the bitten/htdocs directory, but they where not in the new hosts bitten/htdocs or anywhere else.

Tried to remember how I installed bitten (apt-get, ez_install or pip).  Using dpkg --list | grep bitten discovered I had used apt-get.

Uninstalled bitten and re-install using apt-get.  Checked the bitten/htdocs directory.  Still no excanvas.js or jquery.flot.js.

Uninstalled bitten using apt-get.  Installed bitten via:

• svn check-out http://svn.edgewall.org/repos/bitten/tags/0.6 bitten-0.6
  
• cd bitten-0.6
  
• sudo python setup.py install
  

Check bitten/htdocs, excanvas.js and jquery.flot.js now exist.

Re-imported the backup data from the old host and retest, and we have graphs.

Thanks.

I had this problem before. Debian (and Debian-based distros) package flot and
other JS library separately. You will find them in /usr/share/javascript/. Flot
is in /usr/share/javascript/flot/

I created (or did the trac-bitten package to it?) symbolic links in
/usr/share/pyshared/bitten/htdocs/ to flot and excanvas and the plots worked
again.
