Lets check to see if the data is being processed now by running the following and post back the results.
Actually that is a good sign - those directories should be nearly empty. When they start filling up, it means performance and check result data is not being processed by Nagios.
To be clear, are you asking if it is possible to recover the performance data that wasn't graphed to fill in the gaps? If that is what you are asking then the answer is most likely no, unfortunately.
