custom string value at top of bar.

[cuddle-sujeet]

I have gone through the issue: How to let the Y axis shows is not only a number, but the custom string #1003
whose solution states that I should set valueFormatter in ChartDataSet.
My Problem is that I need to set the values on top of these bar with a custom stringvalue coming from webService. From the implementation I see that the value formatter is being applied to the "values" of the chartDataEntry.

Can't we some how use the DataValue as provided in the chartDataEntry init method.
BarChartDataEntry(value: value, xIndex: index, data: displayValue)

I need to set this "displayValue" on top the barChart.

Also I have noticed that the same can be done in android as the CustomerFormatter.

String getFormattedValue(float value, Entry entry, int dataSetIndex, ViewPortHandler viewPortHandler) .

where the formatter has the access to the "entry" which is same as the "data" in swift method BarChartDataEntry(value: value, xIndex: index, data: displayValue).

@arjenbolten No ..had to move to other alternative, I am using the ChartMarker to show the information as bubbles on top of it.

Just use dataSet.valueFormatter in Chart 3.0. it's more flexible now.
