Hi,

Please try the following code:

private void Form1_Load(object sender, EventArgs e)
{
    NChartControl cc1 = GetChartControl();

    // remove default panels
    cc1.Panels.Clear();

    NCartesianChart chart = new NCartesianChart();
    cc1.Charts.Add(chart);
    chart.Enable3D = false;
    chart.Projection.SetPredefinedProjection(PredefinedProjection.OrthogonalHorizontalLeft);

    NBarSeries bar = (NBarSeries)chart.Series.Add(SeriesType.Bar);
    bar.Values.Add(7.094);
    bar.Values.Add(3);
    bar.Values.Add(4.55);
    bar.Values.Add(1.453);

    // no need to add labels if you just want to show the bar values
    // bar.Labels.Add("7");
    // bar.Labels.Add("3");
    // bar.Labels.Add("4");
    // bar.Labels.Add("1");

    // tell the chart to show the bar values in the data labels
    bar.DataLabelStyle.Format = "<value>";

    // show the labels inside the bars
    bar.DataLabelStyle.ArrowLength = new NLength(-2);
    bar.DataLabelStyle.TextStyle.StringFormatStyle.HorzAlign = Nevron.HorzAlign.Right;

    // hide the label arrow
    bar.DataLabelStyle.ArrowStrokeStyle.Width = new NLength(0);

    // hide the label backplane
    bar.DataLabelStyle.TextStyle.BackplaneStyle.Visible = false;
}
