Options for the Pie chart.

C#

public class PieOptions : Options

VB.NET

Public Class PieOptions
    Inherits Options

The Options property returns an instance of this class when ChartType is Pie. This class doesn't add any option to the shared options defined in Options.

Example:

this.chartJS1.ChartType = ChartType.Pie;

var options = (PieOptions)this.chartJS1.Options;
options.Legend.Position = HeaderPosition.Left;
options.Title.Text = "Market Share";

Constructors

PieOptions()

Default constructor.

Creates a standalone PieOptions set that is not yet attached to a ChartJS control. Assign it to the Options property of a pie chart.

Example:

var options = new PieOptions();
options.Legend.Display = false;

this.chartJS1.ChartType = ChartType.Pie;
this.chartJS1.Options = options;

PieOptions(chart, defaults)

Constructs a new instance of the PieOptions set.

Name	Type	Description
chart	ChartJS	The ChartJS that owns this set of options.
defaults	Options	Default options to copy from. Can be null.

When defaults is not null, the properties shared with it (for example Title, Legend or Tooltips) are copied into the new instance, which is how the chart preserves the common settings when ChartType changes. The ChartJS control creates this instance automatically when ChartType is Pie.

Example:

var options = new PieOptions(this.chartJS1, this.chartJS1.Options);
options.Tooltips.Enabled = false;
this.chartJS1.Options = options;
