#Property Value
Type | Description |
---|---|

A Series |
#Remarks
The Points property provides access to a collection of data points that belong to an individual series. The SeriesPointCollection class represents the series point collection and allows you to manage (add, remove, access via indexer notation, etc.) individual series points (instances of the SeriesPoint class) within the collection.
Important
The series Points collection may provide series points that represent data source objects. These points are generated on the first getting of series points. For performance reasons, it is strongly recommended not to request series points when the series is data bound.
The Chart Control does not generate series points until it loads a data source. Use the Chart
The series can sort its points that have qualitative arguments before displaying them using the SeriesBase.SeriesPointsSorting) and SeriesBase.SeriesPointsSortingKey properties. Refer to the Sorting Data guide for more information.
#Example
The following example demonstrates how to create a ChartControl with two series of the SideBySideBarSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.
Then, add the following code to the Form.Load event handler.
Note
A complete sample project is available at https://github.
using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...
namespace SideBySideBar2D {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
// Create an empty chart.
ChartControl sideBySideBarChart = new ChartControl();
// Create the first side-by-side bar series and add points to it.
Series series1 = new Series("Side-by-Side Bar Series 1", ViewType.Bar);
series1.Points.Add(new SeriesPoint("A", 10));
series1.Points.Add(new SeriesPoint("B", 12));
series1.Points.Add(new SeriesPoint("C", 14));
series1.Points.Add(new SeriesPoint("D", 17));
// Create the second side-by-side bar series and add points to it.
Series series2 = new Series("Side-by-Side Bar Series 2", ViewType.Bar);
series2.Points.Add(new SeriesPoint("A", 15));
series2.Points.Add(new SeriesPoint("B", 18));
series2.Points.Add(new SeriesPoint("C", 25));
series2.Points.Add(new SeriesPoint("D", 33));
// Add the series to the chart.
sideBySideBarChart.Series.Add(series1);
sideBySideBarChart.Series.Add(series2);
// Hide the legend (if necessary).
sideBySideBarChart.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;
// Rotate the diagram (if necessary).
((XYDiagram)sideBySideBarChart.Diagram).Rotated = true;
// Add a title to the chart (if necessary).
ChartTitle chartTitle1 = new ChartTitle();
chartTitle1.Text = "Side-by-Side Bar Chart";
sideBySideBarChart.Titles.Add(chartTitle1);
// Add the chart to the form.
sideBySideBarChart.Dock = DockStyle.Fill;
this.Controls.Add(sideBySideBarChart);
}
}
}
