I am trying to add a Pie Chart to a Telerik report for the first time and I am having an issue with that chart being cropped on the right-hand side just after the legend starts. I have included a screen image of the issue.

I have added the pie chart through the design interface and I am populating the data the the OnNeedData event. Below is that code.

private void PieChart_NeedDataSource(object sender, System.EventArgs e)

{

//Charts - Columns to Display

string[] GraphColumnsToExport = new string[2] { "ShortLegendTitle", "Data" };

//Charts

DataTable Total = _SharedDataSet.Tables["CurrentYearToDate"].DefaultView.ToTable("tempTableName", false, GraphColumnsToExport);

//Set the Series

Telerik.Reporting.Processing.Chart procChart = (Telerik.Reporting.Processing.Chart)sender;

Telerik.Reporting.Chart defChart = (Telerik.Reporting.Chart)procChart.ItemDefinition;

ChartSeries serie = new ChartSeries();

serie.Type = ChartSeriesType.Pie;

serie.Clear();

foreach (DataRow dr in Total.Rows)

{

ChartSeriesItem item = new ChartSeriesItem();

item.Label.Visible = true;

item.YValue = Convert.ToDouble(dr["Data"]);

item.Name = Convert.ToString(dr["ShortLegendTitle"]);

item.Appearance.Exploded = false;

item.Label.TextBlock.Text = item.Name + " - #%";

serie.Items.Add(item);

}

serie.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels;

defChart.Series.Add(serie);

}

Hi David,

The code you've provided is correct so the problem must be caused by something else. Please try resizing the chart i.e. making it bigger if your report layout allows it. Another thing to try is set its AutoLayout property to True and see if that makes any difference.
On a side note, does the same issue occur in any of the export formats e.g. PDF?

If you're still having problems, please provide us with a runnable report that exhibits the problem and we would advise you accordingly.

Kind regards,

Steve,
I have tried everything you suggested with no luck, although the pie chart does display correctly in the PDF.

I've have created a new project with just the aspx page with a report viewer and the report.

Below is the code:

Default.cs.aspx

using System;

using System.Collections.Generic;

using System.Linq;

using System.Data;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace TelerikPieChartTest

{

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

{

protected void Page_Load(object sender, EventArgs e)

{

DataTable dt = new DataTable();

dt.Columns.Add("ShortLegendTitle", typeof(String));

dt.Columns.Add("Data", typeof(Decimal));

dt.Rows.Add("Spec. Commercial",68.624);

dt.Rows.Add("Middle Market",131.938);

dt.Rows.Add("Personal Lines", 53.453);

dt.Rows.Add("Small Commercial", 542.864);

PieChartTest report = new PieChartTest(dt);

reportViewer.Report = report;

reportViewer.RefreshReport();

}

Hi David,

We will need some more time to further look into this issue. Meanwhile, if you have any other questions, you can ask them in the support ticket system, as we noticed that there is an open discussion on a matter similar to the current. Threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.
