Here is my html source code:

I had figured out that there was something wrong with griphte django :

Traceback (most recent call last):      File "/usr/lib/python2.6/site-packages/django/core/handlers/base.py", line 111, in get_response
    response = callback(request, *callback_args, **callback_kwargs)      File "/opt/graphite/webapp/graphite/render/views.py", line 104, in renderView
    seriesList = evaluateTarget(requestContext, target)
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 10, in evaluateTarget
    result = evaluateTokens(requestContext, tokens)
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 21, in evaluateTokens
    return evaluateTokens(requestContext, tokens.expression)
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 28, in evaluateTokens
    args = [evaluateTokens(requestContext, arg) for arg in tokens.call.args]
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 21, in evaluateTokens
    return evaluateTokens(requestContext, tokens.expression)
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 28, in evaluateTokens
    args = [evaluateTokens(requestContext, arg) for arg in tokens.call.args]
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 21, in evaluateTokens
    return evaluateTokens(requestContext, tokens.expression)
  File "/opt/graphite/webapp/graphite/render/evaluator.py", line 24, in evaluateTokens
    return fetchData(requestContext, tokens.pathExpression)
  File "/opt/graphite/webapp/graphite/render/datalib.py", line 224, in fetchData
    dbResults = dbFile.fetch( timestamp(startTime), timestamp(endTime) )
  File "/opt/graphite/webapp/graphite/storage.py", line 298, in fetch
    (timeInfo,values) = whisper.fetch(self.fs_path, startTime, endTime)
TypeError: 'NoneType' object is not iterable

This doesn’t appear to be a bug in Cubism. I recommend trying Stack Overflow if you want help.

Also, if your dashboard and Graphite install are on separate servers, make sure you have Access-Control-Allow-Origin: * enabled on Graphite so that the results are accessible.
