No, it is not (yet) supported. Many people have suggested it and it wouldn't surprise me if such a feature will make it into a next release. Mind that it is often best to create another database, especially if you want the extra DS to accomodate stats for another interface.

Suggestion: Make sure you know what graphs you would like to show. You probably want the default 400-pixel wide graphs. Each pixel should have a corresponding CDP in the database. For instance: 400 CDPs of 1 PDP each ( 1 day, 9 hours, 20 minutes) 400 CDPs of 24 PDPs each ( 33 days, 8 hours) 400 CDPs of 288 PDPs each (400 days) HTH -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
