I can see status informatoin for services that I monitor on "service Status" page for each host. but when I click on graphs there are no data on graphs. it shows empty graph. please let me know how to troubleshoot this.

Here is some information regarding my setup

First of all, do those checks missing graphs report performance data?
To find out, go to --> Home --> Service Details --> click on one of the broken services --> Advanced Tab --> Advanced Status Details --> Performance Data. You should see some performance data text in that field, if not, then the problem is with the plugin itself and not the graphing engine.

If perfdata is being reported, then we need to check some logs:

Does the graphs display any errors, perhaps mentioning a template? Could you send us a screenshot of the graph associated with the service noted above? Also, what is the output of the following:
