Hi. I'm tring to create a piechart in a webapplication.

I set objectdatasource of pie chart correctly (i suppose ) but when i open my web page appear only the background of the diagram.

first question: is there a way to check i set correctly the objectdatasource and if the piechart read data in the correct way?

second question: how can i set x and ydata of my chart?

thanks

How can i do this?

Is there any example in MasterChart demo who show a bind Chart-DataBase or chart-Table?

Tanks

I've yet done what you write me. But list of databind is empty.

I use 3.2 demo version (i'm testing the library) of Masterchart

Are there some examples about binding of chart and database,table or some other tipe of datasource?

from my source code:

 this.PieChart1.OuterLabels = dataTableChart.Columns[1]; 

error:

Cannot implicitly convert type 'System.Data.DataColumn' to 'System.Collections.IList'.
An explicit conversion exists (are you missing a cast?) 

What type of cast is correct?

ObjectDataSource worked fine in our test:

TestDataBO.cs

using System.Collections.Generic;

public static class TestDataBO
{
	public static List<TestDataItem> GetItems()
	{
		List<TestDataItem> items = new List<TestDataItem>();
		items.Add(new TestDataItem(33, "test"));
		items.Add(new TestDataItem(77, "label"));
		items.Add(new TestDataItem(55, "another one"));
		return items;
	}
}
 

TestDataItem.cs

/// <summary>
/// Summary description for TestDataItem
/// </summary>
public class TestDataItem
{
	public TestDataItem(double data, string label)
	{
		this.data = data;
		this.label = label;
	}

	public double Data
	{
		get { return data; }
		set { data = value; }
	}

	public string Label
	{
		get { return label; }
		set { label = value; }
	}

	private double data;
	private string label;
}
 

Drop an ObjectDataSource onto the form, configure it, select TestDataBO as the business object and choose GetItems() as the SELECT method. Now if you select the piechart in the designer, you should be able to select the ObjectDataSource instance from the DataSourceID property drop-down, and see Data and Label as available options in the drop-down for the various Field properties.

I hope that helps,
