I debugged through Chart.php and found the problem there. All the dates in Chart.php Line 133 are kind of floats with a comma as the decimal mark and the json_encode() three lines further creates rubbish as it takes the comma as a separator.
The comma as decimal mark is the same reason why the calculation in getMaxValue() does not work.
