View Graphs in Reports

In some reports, not in others.

[eWhisper]

Anyone have an idea why the 'view graphs' for reports doesn't exist all the time?

Sometimes it's there, other times it's not.
It's not account based.
It's not spend based.
It's not report based.
It's not account age based.
It doesn't seem to be time based.

How can I make the view graphs show up consistently?
Ideas?

Officially my first post, and I'm answering a question for a Mod. Awesome.

The graphing function works for every report type except "summary". Try daily, monthly and yearly and it will consistently work.

There are lots of features in AdWords that seem to be account specific. Another example - Find and Edit Ad Text under Tools -> Modify Your Campaigns
