[SOLVED] Zoom area not working correct (with RRDTool 1.4.5)

[seco]

When zooming graphs, showed period is not corresponding to zoomed area.

ie: if i want to zoom from 12:00 pm to 12:00 am, i will see graph from 1:40pm - 1:40 am

From my point of view you're using a buggy version of RRDtool. I assume it is RRDtool v1.4.5 that you're using.
The distance between the graph area and the right graph border is different (smaller) than usual. The zoom code itself will always calculate the different timestamps by using a fixed value for that distance.
Try to use another RRDtool version to verify that. (e.g. RRDtool 1.4.7)

System (FreeBSD 9.0-RELEASE) was compiled @ Tue Mar 27 09:14:02
RRDTool was build from FreeBSD ports

Code: Select all

# pkg_info | grep rrdtool 
rrdtool-1.4.5       Round Robin Database Tools
# rrdtool -v
RRDtool 1.4.5  Copyright 1997-2010 by Tobias Oetiker <tobi@oetiker.ch>
               Compiled Mar 28 2012 15:05:16

At that moment in FreeBSD port tree actual version of RRDTOOL was:
> Revision 1.44: download - view: text, markup, annotated - select for diffs
> Fri Feb 4 10:20:53 2011 UTC (15 months, 1 week ago) by sylvio

and only 7 days ago this port was updated (to RRDTOOL 1.4.7)
> Revision 1.45: download - view: text, markup, annotated - select for diffs
> Mon May 7 18:51:01 2012 UTC (7 days, 12 hours ago) by sylvio
> Diff to: previous 1.44: preferred, colored
> Changes since revision 1.44: +2 -2 lines
> - Update to 1.4.7

OK, lets try to update FreeBSD ports tree and RRDtool package:

Code: Select all

# portsnap fetch update  
  Updating from Fri Apr 13 10:12:26 EEST 2012 to Tue May 15 09:45:14 EEST 2012.
# /usr/libexec/locate.updatedb 
# portupgrade -R rrdtool-1.4.5
# rrdtool -v
RRDtool 1.4.7  Copyright 1997-2012 by Tobias Oetiker <tobi@oetiker.ch>
               Compiled May 15 2012 10:47:56

After that zooming worked well.

Thanks a lot!
