How to create High chart of type Bubble?

[gowthamsenmca]

Hi,

I am using Jasper Studio 5.5. The Bubble chart is not available directly when we use "html5" chart element.

But in the  help, they have mentioned that we can create "Bubble" chart using customization options.

Can any one please guide me in how to acheive this?

Best Regards

Gowtham

                   final DateFormat dateFormat = DateFormat.getDateInstance();
                  domainAxis.setNumberFormatOverride(new NumberFormat()
         {

        public StringBuffer format(double number, StringBuffer toAppendTo, FieldPosition pos)
       {
               return format((long) number, toAppendTo, pos);
        }
 
       public StringBuffer format(long number, StringBuffer toAppendTo, FieldPosition pos)
      {
               return dateFormat.format(new Date(number), toAppendTo, pos);
      }
 
      public Number parse(String source, ParsePosition parsePosition)
     {
            throw new UnsupportedOperationException();
     }
  });
 }

The suggestion in the comments above apparently are related to the Standard chart type bubble, if I am not mistaken.
