Code for testing the bug

I have been getting a PHP Notice when rendering the TChart at teechart\sources\axis\AxisLabels.php on line 514.

Making the following change stops the PHP Notice


512                 $tmpResult = number_format((float)$value,$decimals,
513                 self::$LOCALE['decimal_point'],
514                 self::$LOCALE['thousands_sep']);

The former image I have posted was incorrect.

I have found the problem. 

It is not linked to the result of PHP DateTime::getTimestamp() method but to the YValue which is been returned by the Oracle query.

As my Oracle database was configured to Brazilian localization parameters the number is been returned with a comma instead of the decimal point. So this is the reason for the non well formed number message.

I suggest to Steema that include in the documentation of TeeChart for PHP that the values to be furnished to TeeChart methods and properties should be formatted on the American localization parameters, using decimal points.
