I've got a stacked column chart which looks pretty good.  I want to add a percentage value to the toolText for 2 of the columns.  I've tried putting in a custom tooltext value but the value appears as 123456, while the value in the tooltip for the other columns looks like £123.4K so it doesn't look right.

I either want to get the same method for formatting the value using K / M or I want to be able to get the existing tooltip and just append my custom % value to it.

I don't want to restrict my charts to always use a specific value format - depending on the value in the columns we might want to show M / K or just units so I want to use the same method to calcualte the value as FusionCharts uses to make sure it's always consistent.

Can anyone suggest a solution to this problem?

Thanks
