[drraw-users] RRA Types Other than MIN, AVERAGE, MAX and LAST?

[Joel Krauska]

Howdy,

I've been experimenting with Holt-Winters forecasting using RRDtool.
http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html

drraw seems hardcoded to only support the normal four RRA types.
MIN, AVERAGE, MAX and LAST

When Using Holt-Winters, you get these new additional types:
HWPREDICT
MHWPREDICT
SEASONAL
DEVSEASONAL
DEVPREDICT
and
FAILURES

Can these be added to be supported options in drraw?

I can manually tweak a config file, but then the next time I edit it, it's overwritten with MIN.

Thanks,

Joel
