[rrd-users] Changing X-Axis

[Francisco Abel Perea Mora]

Tobi,

It's to complicated try ti change original RRDTool source code to allow
another X-Axis data?

It will be really nice feature to add to RRDTool. Could we start a
development group in that subject?

Best regards

Francisco Perea
Electrical engineer, MSc.
