How to change donut chart labels

[Arturo]

Good afternoon everyone, I am trying to make a donut chart and I have managed to fill it with the values of a datatable, the problem I have is when showing the legends, it always gives me the same value to show. How can I make the labels show as they should be? Thank you

Hi Arturo,

In order to have different names for the series items of the Donut chart, you have to pass the name of the column holding the desired values to the NameField property of the chart.

For example:

        <telerik:RadHtmlChart ID="RadHtmlChart1" runat="server">
            <PlotArea>
                <Series>
                    <telerik:DonutSeries Name="Series 1" DataFieldY="valuesColumn" NameField="namesColumn">
                    </telerik:DonutSeries>
                </Series>
            </PlotArea>
        </telerik:RadHtmlChart>

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            RadHtmlChart1.DataSource = GetData();
            RadHtmlChart1.DataBind();
        }
    }

    private object GetData()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("valuesColumn");
        dt.Columns.Add("namesColumn");

        dt.Rows.Add(20, "Correctivo");
        dt.Rows.Add(20, "Verficacion");
        dt.Rows.Add(20, "Adaptaciones");
        dt.Rows.Add(20, "Garantia");

        return dt;
    }
