Description Max 2014-01-23 06:30:10 EST 
1. Javascript code is written using my local (german) decimal separator, which is a comma. 

Sample for wrong code, produced using the built in chart editor's export to HTML5 javascript function): 
  Chart1.axes.bottom.labels.format.font.style="10,667px Arial";
Series Data are ok in this case. 


2. Javascript data is written using my local (german) decimal separator, which is a comma. 

Sample for wrong data, produced by built in chart editor's export series data to JSON preview function: 
{ "chart": [
  {
   "series": {
   "name":"P4_NN_ROK",
   "color":"#0000FF",
   "point": [
     { "value":165,13445, "x":38831,750775463 },
     { "value":165,1343, "x":38831,7924537037 },
     { "value":165,1346, "x":38831,8341319444 },
     { "value":165,1329, "x":38831,8758101852 },

Btw: above example used a date axis. The windows date format you are writing here is pretty useless. Do you think it might be possible to export datetime data so they are automatically recognized by TeeChart Javascript?

This is now fixed.
A workaround is to set DecimalSeparator to a "." and restore it again later:

var Old :Char;

  // JSON Decimal separator is always a dot "."
  Old:=FormatSettings.DecimalSeparator;
  FormatSettings.DecimalSeparator:='.';

  try

   (...use TeeJavaScript.pas  TJavascriptExportFormat class...)

  finally
   FormatSettings.DecimalSeparator:=Old;
  end;

Fixed. 

FormatSettings.DecimalSeparator is now set to "." (dot), and restored after creating the JavaScript code.
