Script broken in PHP 7.1

[dterweij]

Warning: Illegal string offset ‘XAxisDisplay’ in /class/pData.class.php on line 73

and many many more PHP fatal errors.

Also:

Uncaught Error: Cannot use string offset as an array in ... pData.php:80

[greenbicycle]

This is due to the fact that many arrays are initialized as strings. PHP5.6 would tolerate that, but php7.0 onward will not.
