XAxis Label inside the bar

[Tobin]

Hi Telerik.

1. How do i put XAxis label (O in styling chart element) inside the bar (P in styling chart element) instead in bottom ? I have difficulty since my XAxis data is long.

2. How do i format Series Item Label (r in styling chart element) to number with decimal?

3. My bar chart bound to empty dataset, how to make sure that the chart will show EmptyChartMessage, since my case it didnt show.


Thank for your help.

Hello Tobin,

It is not possible to move the Axis Labels inside a bar nor any other chart as those labels are designed to display information on the Axes. If you prefer, you can hide them by setting

this.radChart1.PlotArea.XAxis.Appearance.LabelAppearance.Visible = false;

You can customize the items' labels by handling the Chart's ItemDataBound event:

public partial class Form1 : Form
{
    double[] sampleData = new double[] { 0, 10, 20, 30, 40, 5, 20, 35, 50, 65 };

    public Form1()
    {
        InitializeComponent();

        this.radChart1.PlotArea.XAxis.Appearance.LabelAppearance.Visible = false;
        this.radChart1.ItemDataBound += new EventHandler<ChartItemDataBoundEventArgs>(radChart1_ItemDataBound);

        this.radChart1.DataSource = sampleData;
        this.radChart1.DataBind();
    }

    void radChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
    {
        e.SeriesItem.Label.TextBlock.Text = "New Label";
        e.SeriesItem.Label.Appearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Inside;
    }
}

The EmptyChartMessage shows up only in case there are no series in the RadChart.Series collection (and none are generated by the binding). Having no ChartSeriesItems in the series does not count as empty chart.
