y-axis scale labels in auto-scale mode

[frackers]

I'm using autoscale mode extensively but I'm finding it frustrating that the y-axis scaling will only display integers. If I have a value that changes by less than 1 unit across the range of the graph, I get the y-axis label repeated.

Note how the value 25 is repeated - I would guess from the 'Present Voltage' value that the lower label in the y-axis should be 24.9 not 25!

I'm running 0.8.7b under Linux.

Please post debug output from graph management for this graph

This issues was addressed in "feature#0000954: implement --alt-y-grid graph option", which should be in upcoming versions of Cacti... Although oddly, it says it was added to 0.8.7c, but not present. It IS present in the SVN though.

I suppose that this was my fault.

I've been trying to determine how to reference changes to bug refs but the SVN browser doesn't use TRAC so I can't see when the changeset was appied and to which modules.

Is there anyone who could indicate the relevant modules so I can make a minimal change to my Gentoo install pending a new version appearing in their stable tree.

Thanks

I'm confused. I have a fully patched Cacti 0.8.7g installed on Ubuntu Linux 10.10 (current version).
Cacti feature#000954, in subversion revision 4451, which was checked in 2008-02-01 14:29:02 -0800,
is not included in my Cacti installation. (This feature adds an "--alt-y-grid" option for rrdtool, which
I have confirmed experimentally does correct a problem I'm having with duplicate integers on the Y axis.)

My evidence for this: I have not found the feature in the installed changelog for 0.8.7g,
the new fields that the revision defines in mysql table graph_templates_graph
( t_alt_y_grid and alt_y_grid) are absent, and the changes it makes to various php scripts are absent.

I checked the online Cacti svn repository for branches/0.8.7/cacti.sql :
http://svn.cacti.net/viewvc/cacti/branc ... w=annotate
but the changes are not reflected there either:
<snip>
1422 : gandalf 4329 t_scale_log_units char(2) default '0',
1423 : scale_log_units char(2) default NULL,
1424 : raxnet 695 t_auto_scale_rigid char(2) default '0',
1425 : auto_scale_rigid char(2) default NULL,
1426 : t_auto_padding char(2) default '0',
<snip>

So, I conclude that feature#0000954 / revision 4451 did not make it into the release for 0.8.7.
Can anyone shed some light on this? Can I apply the missing changeset as a patch, or would
there possibly be dependancies on some other changeset? Is there a reason why this wasn't
included in the release?

Thanks for any help,

the new fields that the revision defines in mysql table graph_templates_graph

This option seemed to be implemented in the past, but omitted for some reason (I don't know).

I tried some test.
When zoomed one graph, label for y-axis is duplicated.

So I added the option to 'lib/rrd.php'.

$scale = "--alt-autoscale-max --alt-y-grid" . RRD_NL;

It fixed the problem. Wow.

But, for another (zoomed) graph without problem,

alt-y-grid_3.png (15.91 KiB) Viewed 4978 times

changed to this..

alt-y-grid_4.png (7.39 KiB) Viewed 4978 times

That's tricky.

Greetings Cacti Gurus,

I am very interested in applying this patch and would like to find out if any potential conflicts exist with post-patches if this patch is applied.

best regards
Stephen

As the patch introduces a db change, it's a bit tricky. Nevertheless, everything necessary should be included in that very SVN update
