A negative number with space is treated as text in data module.

[ddragula]

Expected behaviour

Text describing a number containing a space as a thousand separator should be treated by the data module as a number regardless of whether it is positive or negative.

Actual behaviour

Text describing a number containing a space as a thousand separator is not treated by the data module as a number when it is negative.

Solution : https://jsfiddle.net/tse1zyu6/3/

beforeParse: Highcharts.DataBeforeParseCallbackFunctionSince 6.1.0
A callback function to modify the CSV before parsing it. Return the modified string.

Defaults to undefined.

Try it
Modify CSV before parse

Hi @AmoghAnantha, thanks for the suggestion. However, beforeParse works only for CSV, and the problem is general in the data module, e.g. for tables:
