Less than sign inside items and labels of graph make them broken

[coozoo]

Hi sorry for that very small bug :)
If set less than sign (<) for label and item it will make them broken.
Greater than sign works fine(>).
In label and item it behaves in little bit different way if replace with escape sequences please see below.

1. Example for an old version 0.8.8 - correct result
   

In graph debug it's converted to this:
--vertical-label="test(down if <1)" \ GPRINT:a:MIN:"MIN(<1)\:%8.2lf %s" \

So pay attention to double quotes inside command.

2. Current result version 1.0.4 - incorrect result
   

In graph debug it's converted to this:
--vertical-label='Sitecore State (down if <1)' \ GPRINT:a:MIN:'DOWN(<1)\:%8.2lf %s' \

Pay attention that in new version it's single quoted.

3. Current result version 1.0.4 escape sequence - incorrect result
   

In graph debug it's converted to this:
--vertical-label='Sitecore State (down if <1)' \ GPRINT:a:MIN:'DOWN(lt;1)\:%8.2lf %s' \

You can see that escaped works fine for label, but inside item ampersand sign is missed that's why workaround doesn't work here.

Thank you

Well, we have been trying to simplify the lib/rrd.php code. We escapted the title, but not the axis or the legends. So, I'm not surprised. Thanks for reporting. Should not take to long to find the proper approach to resolving this.

Please test with the latest lib/rrd.php and provide feedback. Thanks for reporting.

Hi thanks, I've tested it little bit
Less than fixed
but another side effect appeared
Line breaks (Insert Hard Return checkbox <HR>) for items are not correctly working there is n (suppose it's somehow related to replacing backslash in \n) at the end of each string

And you can see that there is case that sometimes linebreaks works but still n at the end

In both cases rrd command, on webpage from debug, looks identically:
GPRINT:cdeffa:LAST:'CUR\:%8.2lf %s'\n \
So i'm not sure what the reason of this.
thank you
