This pages gives me a lotta php errors:

It helps if line 58 is changed to:

 $this->Data = array();

and line 88 to:

{ $Result = ""; foreach($Values as $Key => $Value) { if ( $Value != VOID ) { $Result=array(); $Result[] = $Value; } } return($Result); }

But additional errors keep popping up after this in pDraw.class.

Seems to be a PHP version issue (using PHP 7.3.11).

The pchart plugin used is ancient and not maintained as it seems (latest release is from 2014).

https://github.com/dmelo/pChart seems to contain a more recent version.

[wvdvegt]

Tried this version (renamed all *.php files to *.class and moved them into the class folder of the pChart plugin and the number of warning is reduced and a graph is showing.

Perhaps it's better to keep the pChart code as-is and change all *.class file references to .php ones

NOTE: the remaining warning is a typo in PData.class.

function convertToArray($Value)
{ return array($Values); }

should read:

function convertToArray($Value)
{ return array($Value); }
