I had to think about that for a minute, it might not be clear to a new user. Just to clarify, you mean : Paint outbound traffic as positive using background colour Paint inbound traffic as positive with inbound data colour Paint inbound traffic as negative using background colour Paint outbound traffic as negative using outbound data colour Thus the Y axis will scale on the positive side to include the max value of inbound or outbound traffic, and it will scale on the negative side to include the min value of -ve inbound and -ve outbound traffic. Painting the data with the background colour doesn't draw anything visible, but it will cause the graph to autoscale to include it. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
