[rrd-users] problem with values when using width

[Andreas Horndasch]

Hi everybody,

since four days I have problems using rrdtool with width and average.

When i drow a graph with a width the result is an other as the result of a graph without width...

For example:
Using width value is: 99,92
Not usind width value is: 99,82

The start und the end values are the same.


I created my database with:
<---
RRDs::create($rrdpfad, "-b 1016182000", "-s 60", "DS:values:GAUGE:1800:U:U",
  	      "RRA:AVERAGE:0.5:1:12096",
  	      "RRA:AVERAGE:0.5:6:17520");
<---

To get the values I use:
<---
    my ($averages, $xsize, $ysize) = RRDs::graph("$bild", "--imgformat", "PNG", "--start", "$start","--end","$end",
                                                 "--title= Values in Prozent", 
                                                 "DEF:values=/opt/rrd/verfuegbarkeit/".$host.".rrd:values:AVERAGE",
                                                 "CDEF:ava=values,UN,0,values,100,*,IF",
                                                 "LINE2:ava#0000FF:Verfügbarkeit",
                                                 "GPRINT:ava:AVERAGE:Verfügbarkeit im Zeitraum\\: %3.2lf%s \\j",
                                                 "COMMENT:$von - $bis"
                                                 );
<---

OR (with width)

<---
    my ($averages, $xsize, $ysize) = RRDs::graph("$bild", "--imgformat", "PNG","-w 10000", "--start", "$start","--end","$end",
                                                 "--title= Values in Prozent", 
                                                 "DEF:values=/opt/rrd/verfuegbarkeit/".$host.".rrd:values:AVERAGE",
                                                 "CDEF:ava=values,UN,0,values,100,*,IF",
                                                 "LINE2:ava#0000FF:Verfügbarkeit",
                                                 "GPRINT:ava:AVERAGE:Verfügbarkeit im Zeitraum\\: %3.2lf%s \\j",
                                                 "COMMENT:$von - $bis"
                                                 );
<---


Using the width of 10.000 will give a bedder result...

But this result could not be printed in an htmlpage...


Some ideas how to get the best result without using width?


Thanks for help.

Andreas
