  Hello,
  
  I am working with a RadChart as a stacked bar style and showing the DataTable below the chart which shows value percentages. However, I am using some values with large range differences and this means several of my data items are less than 1% but show as 0% in the DataTable. Is it possible to change the DataTable values to show percentages less than 1%?
  
  Thanks

  Depending on the ratio of sub 1% values, you could set AutoScale=false for the Y-axis and then set an arbitrary value for the YAxis.MaxValue that would better display the smaller values and just let the large values shoot through the roof.
  
  Default.aspx.cs:
  

  using System;

  using System.Web;

  using System.Web.UI;

  using System.Web.UI.WebControls;

   

  using System.Data;

  using System.Configuration;

  using System.Web.Security;

  using System.Web.UI.WebControls.WebParts;

  using System.Web.UI.HtmlControls;

  using Telerik.Web.UI;

  using Telerik.Charting;

   

  public partial class Default : System.Web.UI.Page

  {

      protected void Page_Load(object sender, EventArgs e)

      {

          if (!Page.IsPostBack)

          {

              LoadChart();

          }

      }

   

      private void LoadChart()

      {

          RadChart1.Series.Clear();

   

          ChartSeries c = new ChartSeries("Series1", ChartSeriesType.StackedBar);

   

          c.AddItem(.1);

          c.AddItem(10);

          c.AddItem(.3);

          c.AddItem(25);

          c.AddItem(.6);

          c.AddItem(75);

          c.AddItem(.2);

          c.AddItem(150);

          c.AddItem(.8);

          c.AddItem(200);

   

          RadChart1.AddChartSeries(c);

   

          RadChart1.PlotArea.YAxis.AutoScale = false;

          RadChart1.PlotArea.YAxis.MaxValue = 25;

      }

  }
