sorry, i don't know that right now without additional investigation. a quick search reveals http://www.zabbix.com/forum/showthread.php?t=15378 - you could take a look at that patch and figure out where it changes the font scaling, maybe

Richlv, I have looked at this, unfortunately
its doesn't helped; looking at that post I only
can change the size of legend.

I have looked for the string "fontsize" inside
the files (with the command grep -ir fontsize ./);
into zabbix php frontend directory, but once again,
I didn't found how to change the size of title.

Thanks anyway!

Guys,

I discovered that that function wich write
the texts in the graphs, is: function imageText($image, $fontsize, $angle, $x, $y, $color, $string); which is in php script graphs.inc.php;
that is inside the directory /.../zabbix/include/graphs.inc.php
;

So I made a change that source code in this function,
adding this:

function imageText($image, $fontsize, $angle, $x, $y, $color, $string){
$gdinfo = gd_info();

//Search for the paterner wich are at the graphs title
//If add
if(strstr($string,"(") && strstr($string,")") && strstr($string, ":")){
$fontsize = 16;
}

So a I recieved the expected result, as show in the
pictures below:

Graph before change:


Graph after change:


PS: I searched for for all php scripts and
classes which call the funciton imageText
and after change the parameter fontsize;
I get change in everything less int the title.

Does somebody know a better solution?
