[rrd-users] Re: HRULE/Upper limit

[DJ Gregor]

Hello again,

Right now, your Y-axis shows data in kilobytes, so "250 k", for 
example.  If you want this to show up as "250 M", you will need to use 
a CDEF to multiply the values stored in your RRD by 1024.  Add 
",1024,*" onto the end of the appropriate CDEF's.  You could also 
divide by 1024 and use --vertical-label to mention that the data is in 
megabytes.
