Subject: [PATCH] Update Settings.php

Added the function to scale the Labels also in decimals.
sometimes You have values with more than 2 decimals....
Usage:

$settings = new Settings();
$settings->setDecimals(3);
$lineGraph = new Linechart();
$lineGraph->setSettings($settings);

keep in mind that padding also need to be adjusted....
if the float value is the following 2.24537256
then:
$settings->setDecimals(8);
then the padding should be at least 10
$settings->setPadding(10);
