Hi~
I try to avoid to overlap a axis's label using LabelFitMode.RemoveOverlap.
But it is delayed applying.

My code and a screenshot is here.
Thanks for your help.



private void RemoveOverlapLabel()
{
NChart m_Chart = nChartControl1.Charts[0];
m_Chart.BoundsMode = BoundsMode.Stretch;

NStandardScaleConfigurator scaleConfiguratorX = (NStandardScaleConfigurator)m_Chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator;
//scaleConfiguratorX.MajorTickMode = MajorTickMode.CustomStep;

scaleConfiguratorX.LabelFitModes = new LabelFitMode[] { LabelFitMode.RemoveOverlap };

scaleConfiguratorX.AutoLabels = false;
scaleConfiguratorX.Labels.Add("France");
scaleConfiguratorX.Labels.Add("Italy");
scaleConfiguratorX.Labels.Add("Germany");
scaleConfiguratorX.Labels.Add("Norway");
scaleConfiguratorX.Labels.Add("Spain");
scaleConfiguratorX.Labels.Add("Belgium");
scaleConfiguratorX.Labels.Add("Greece");
scaleConfiguratorX.Labels.Add("Austria");
scaleConfiguratorX.Labels.Add("Sweden");
scaleConfiguratorX.Labels.Add("Finland");
scaleConfiguratorX.Labels.Add("Poland");
scaleConfiguratorX.Labels.Add("Denmark");

NBarSeries series1 = (NBarSeries)m_Chart.Series.Add(SeriesType.Bar);
series1.FillStyle = new NColorFillStyle(Color.Crimson);
series1.Name = "Product A";
series1.DataLabelStyle.Visible = false;
GenerateData(series1.Values, 12);

}

private void GenerateData(NDataSeries dataSeries, int count)
{
Random random = new Random();
for (int i = 0; i < count; i++)
{
dataSeries.Add(random.NextDouble() * 99 + 1);
}
}

Hi Inhyuk,

The remove overlap labels mode is not generally intended for public usage. It is used internally in some cases of the value timeline axis and relies on the label z order index. It can be useful with custom labels only as there is a way to assign z order index to labels:

  private void Form1_Load(object sender, EventArgs e)
  {
   NChart m_Chart = nChartControl1.Charts[0];
   m_Chart.BoundsMode = BoundsMode.Stretch;

   NStandardScaleConfigurator scaleConfiguratorX = (NStandardScaleConfigurator)m_Chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator;
   //scaleConfiguratorX.MajorTickMode = MajorTickMode.CustomStep;

   scaleConfiguratorX.CustomLabelFitModes = new LabelFitMode[] { LabelFitMode.RemoveOverlap };

   scaleConfiguratorX.AutoLabels = false;

   string[] labels = new string[] {
            "France",
            "Italy",
            "Germany",
            "Norway",
            "Spain",
            "Belgium",
            "Greece",
            "Austria",
            "Sweden",
            "Finland",
            "Poland",
            "Denmark" };

   for (int i = 0; i < labels.Length; i++)
   {
    NCustomValueLabel valueLabel = new NCustomValueLabel();

    valueLabel.Text = labels[i];
    valueLabel.Value = i;
    valueLabel.Style.ZOrder = i % 2;

    scaleConfiguratorX.CustomLabels.Add(valueLabel);
   }  

   NBarSeries series1 = (NBarSeries)m_Chart.Series.Add(SeriesType.Bar);
   series1.FillStyle = new NColorFillStyle(Color.Crimson);
   series1.Name = "Product A";
   series1.DataLabelStyle.Visible = false;

   GenerateData(series1.Values, 12);
  }

  private void GenerateData(NDataSeriesDouble dataSeries, int count)
  {
   Random random = new Random();
   for (int i = 0; i < count; i++)
   {
    dataSeries.Add(random.NextDouble() * 99 + 1);
   }
  }

for example will remove overlapping adjacent labels. Again this mode is not intended for use in a categorical scale - generally it's intended to remove automatic labels that overlap custom ones.

Best regards,
Bob
