Formatting Negative Currency Y Values

[antdow]

Please can you let me know how I would go about showing a Y Value (e.g. on a column chart) with a slightly different format, specifically currency.

I am using yValueFormat “£#,###,###” to correctly show my values on the charts (e.g. £212,717) however when the result is negative, it is showing is as £-212,717. How can I change this so that the minus sign precedes the currency (i.e. -£212,717)?

I have worked out how to do this (using labelFormatter) for the Y: axis but not for the actual values on the bars themselves.

Thank you very much for your help,

Tony

In this case you can use formatNumber along with labelFormatter or indexLabelFormatter function as shown in this JSFiddle.
