I have a line series displayed on a chart with the y axis set to display percentages.The y axis and the data appears correctly. 

However the labels display the percentage values wrongly e.g. 3 is plotted correctly as 300 % but the label says 33.33%. 

Any way of getting the data labels to display correctly would be much appreciated.

Thanks

Lucy

NCartesianChart barChart = new NCartesianChart();            

barChart.Margins = new NMarginsL(10, 0, 0, 10);            
barChart.Dock = winforms.DockStyle.Fill;            
barChart.BoundsMode = BoundsMode.Stretch;            
 _chartControl.Charts.Add(barChart);            
_currentChart = barChart;             
NStandardScaleConfigurator yScale = (NStandardScaleConfigurator)barChart.Axis(StandardAxis.PrimaryY).ScaleConfigurator;            
yScale.LabelValueFormatter = new NNumericValueFormatter(NumericValueFormat.Percentage);                    
NLineSeries lineSeries = (NLineSeries)barChart.Series.Add(SeriesType.Line);                
lineSeries.DataLabelStyle.Format = "<percent>";            
lineSeries.Values.Add(3);            
lineSeries.Values.Add(4);            
lineSeries.Values.Add(2);                     
barChart.Refresh();             
_chartControl.Refresh();
 
 

Hi,

I found a way around this problem using custom labels thanks, so I don't need any help.

Thanks

Lucy

Hello Lucy,

The format string that you specified:

lineSeries.DataLabelStyle.Format = "<percent>";

instructs the label to display the data point's value as percent of the total for the series. So in this case the chart automatically sums all the values in the data series (3 + 4 + 2 = 9) and displays the value (3) as percent of the sum (9), so 33.33% is correct.
