Ok, I’ve solved the is the wrong way:
easy charts (includes/js/d3.js)
2834 var d3_locale_enUS = d3.locale({
2835 decimal: ".",
2836 thousands: ",",
2837 grouping: [ 3 ],
2838 currency: [ "$", "" ],
2839 dateTime: "%a %b %e %X %Y",
2840 date: "%m/%d/%Y",
2841 time: "%H:%M:%S",
2842 periods: [ "AM", "PM" ],
2843 days: [ "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" ],
2844 shortDays: [ "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" ],
2845 months: [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ],
2846 shortMonths: [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ]
2847 });
2848 var d3_locale_deDE = d3.locale({
2849 decimal: ",",
2850 thousands: ".",
2851 grouping: [ 3 ],
2852 currency: [ "€", "" ],
2853 dateTime: "%A, der %e. %B %Y, %X",
2854 date: "%d.%m.%Y",
2855 time: "%H:%M:%S",
2856 periods: [ "AM", "PM" ],
2857 days: [ "Sonntag", "Montag", "Dienstag", "Mittwoch", "Donnerstag", "Freitag", "Samstag" ],
2858 shortDays: [ "So", "Mo", "Di", "Mi", "Do", "Fr", "Sa" ],
2859 months: ["Januar", "Februar", "M?rz", "April", "Mai", "Juni", "Juli", "August", "September", "Oktober", "November", "Dezember"],
2860 shortMonths: [ "Jan", "Feb", "Mrz", "Apr", "Mai", "Jun", "Jul", "Aug", "Sep", "Okt", "Nov", "Dez" ]
2861 });
2862 d3.format = d3_locale_deDE.numberFormat;
