I am passing csv data into highchart but it failed to render the chart. The csv file contains formatted number such as "100,000" .
See link to the sample code

To avoid this error you can comment a itemDelimiter property like in the first demo. If you want to keep this property you can modify your data and parse proper elements in complete property - see the second demo.String value sent to series.data, expected Number
This happens if using a string as a data point, for example in a setup like this:
series: [{
data: ["3", "5", "1", "6"]
}]
Highcharts expects numerical data values.
The most common reason for this error this is that data is parsed from CSV or from a XML source, and the implementer forgot to run parseFloat on the parsed value.
Note: For performance reasons internal type casting is not performed, and only the first value is checked (since 2.3).
