[rrd-users] How to plan RRD creation from previously acquired data?

[Steve Shipway]

Your problem is that your data are in Scientific format; 'rrdtool update'
wants them as decimals.

Your file says:

1357081200:5.3186666666e+01:1.9346617284e+01

RRDTool wants:

1357081200:53.186666666:19.346617284
