Martynas,
Unfortunately the latest git version is broken for me.
At least in libraries/chart.lib.php on line 5 you use a lower case
filename which does not match in case-sensitive environments.
Some other points:
* Please use curly braces even in situations where they are technically
optional. Not:
if (is_null($options))
return;
but
if (is_null($options)) {
return;
}
* Please make sure you properly escape variables you print to the user.
$sql_query in tbl_chart.php should probably have htmlspecialchars()
In general ... distrust any data you get from the outside.
Most code looks OK though, nice going.
