Previously Cacti 0.8.7b, I have already installed the xampp 1.6.7 which is a application that includes a big package with php 5.2.6, Apache, filezilla and mysql all together at once, so I installed all these softwares on window xp in my computer and later, I installed the Cacti following the standard procedure led by the documentation, I started to work on it but there is a problem with my graphs, and I m afraid that is given to a error messages that comes out from the rrdtool application, the error is the following:

The graph will normally be created from the RRD file. The RRD file is populated via the poller.php which is called by the task scheduler. If the poller is scheduled, then it could be that the data from the device isn't being returned properly so check your cacti logs, put the device in question into debug mode via Console -> Devices -> Edit Device or Console -> Settings -> Device Debug (if you know the id).

Also, make sure that the permissions on the RRD directory are valid for the users attempting to read/write from them. For the poller this may be a different user to the apache web user.
