Re: [rrd-users] newbie rrd question - probably a very old issue

Jason,

if you want to have this, you create TWO rras, one with MIN and one
with MAX consolidation.

in the graph you draw

MIN and stack MAX-MIN on top of it and you get that 'magic' graph
dans seems to be looking for ... it will look odd, since it will
change its 'width' depending on the distance between min and max,
but I can't see how he expects this to work any other way ...

I wonder what his nsdaq graph does if in a single day there is an
extreem high and and extreem low, but there is only a single pixel
in the graph to represent that day ...

cheers
