How to show all labels without grouping?

[Eda]

Hi. I am having a problem with converting the RadChart that we used earlier to ChartView. I am using this code to generate the LineSeries with DataTable.

radChart1.Axes.Clear();

           radChart1.BackColor = Color.White;
           radChart1.ShowPanZoom = true;
           Telerik.WinControls.UI.LineSeries ls = new Telerik.WinControls.UI.LineSeries();
           radChart1.Series.Add(ls);
           ls.DataSource = dt;
           ls.ShowLabels = true;
           ls.ValueMember = "Value";
           ls.CategoryMember = "Label";
           ls.CombineMode = Telerik.Charting.ChartSeriesCombineMode.None;

           foreach (DataColumn dc in dt.Columns)
           {
               if (dc.ColumnName == "LSL" || dc.ColumnName == "USL" || dc.ColumnName == "LWL" || dc.ColumnName == "UWL")
               {
                   DataTable LSLDt = dt.Copy();
                   LSLDt.Columns.Remove("Value");

                   Telerik.WinControls.UI.LineSeries LSLSeries = new Telerik.WinControls.UI.LineSeries();

                   radChart1.Series.Add(LSLSeries);
                   LSLSeries.DataSource = dt;
                   LSLSeries.ShowLabels = false;
                   LSLSeries.ValueMember = dc.ColumnName;
                   LSLSeries.Name = dc.ColumnName;
                   LSLSeries.CategoryMember = "Label";
                   LSLSeries.CombineMode = Telerik.Charting.ChartSeriesCombineMode.None;

                   if (dc.ColumnName.Contains("SL"))
                   {
                       LSLSeries.BackColor = Color.Red;
                   }
                   else if (dc.ColumnName.Contains("WL"))
                   {
                       LSLSeries.BackColor = Color.Yellow;
                   }
               }
           }

           //  radChart1.ShowSmartLabels = true;
           radChart1.Axes.Get<Telerik.WinControls.UI.CategoricalAxis>(0).PlotMode = Telerik.Charting.AxisPlotMode.OnTicksPadded;
           radChart1.Axes.Get<Telerik.WinControls.UI.CategoricalAxis>(0).LabelFitMode = Telerik.Charting.AxisLabelFitMode.Rotate;
           radChart1.Axes.Get<Telerik.WinControls.UI.CategoricalAxis>(0).LabelRotationAngle = 270;
           radChart1.Axes.Get<Telerik.WinControls.UI.CategoricalAxis>(0).ShowLabels = true;
           radChart1.Axes.Get<Telerik.WinControls.UI.LinearAxis>(1).ShowLabels = true;

But I need to show every single detail without grouping the labels. I have attached the way it used to look with RadChart and the new ChartView.

One of my other problems is that, when there is only one category and one Y value, I want to show a dot. But when I give the DataTable(which has 5 rows, all the values and labels are the same) as a source to LineSeries, nothing is shown. It is also attached as a file below. I'd appreciate it if you can help me with these issues.

Right now I am doing it so, I am taking the minutes in to count too. I just have one more question, how can I set up the label format, so that it doesn't show the minutes, only dates?

 

    radChart1.Axes.Clear();

            DateTimeCategoricalAxis ax = new DateTimeCategoricalAxis();
         
            ax.DateTimeComponent = Telerik.Charting.DateTimeComponent.TimeOfDay;
            ax.LabelFormat = "{0:dd.MM.yyyy}";

            ax.PlotMode = Telerik.Charting.AxisPlotMode.OnTicksPadded;
            ax.LabelFitMode = Telerik.Charting.AxisLabelFitMode.Rotate;
            ax.LabelRotationAngle = 270;
            ax.ShowLabels = true;

            radChart1.BackColor = Color.White;
            radChart1.ShowPanZoom = true;
            Telerik.WinControls.UI.LineSeries ls = new Telerik.WinControls.UI.LineSeries();
            ls.DataSource = dt;
            ls.ShowLabels = true;
            ls.ValueMember = "Value";
            ls.CategoryMember = "Label";
            ls.HorizontalAxis = ax;
            radChart1.Series.Add(ls);


            foreach (DataColumn dc in dt.Columns)
            {
                if (dc.ColumnName == "LSL" || dc.ColumnName == "USL" || dc.ColumnName == "LWL" || dc.ColumnName == "UWL")
                {
                    DataTable LSLDt = dt.Copy();
                    LSLDt.Columns.Remove("Value");

                    Telerik.WinControls.UI.LineSeries LSLSeries = new Telerik.WinControls.UI.LineSeries();
                  
                    LSLSeries.DataSource = dt;
                    LSLSeries.ShowLabels = false;
                    LSLSeries.ValueMember = dc.ColumnName;
                    LSLSeries.Name = dc.ColumnName;
                    LSLSeries.CategoryMember = "Label";
                    LSLSeries.HorizontalAxis = ax;
                    radChart1.Series.Add(LSLSeries);

                    if (dc.ColumnName.Contains("SL"))
                    {
                        LSLSeries.BackColor = Color.Red;
                    }
                    else if (dc.ColumnName.Contains("WL"))
                    {
                        LSLSeries.BackColor = Color.Yellow;
                    }
                }
            }

I used LabelFormatProvider so it is OK now.
