ChartArea Class

.NET Framework 4.6 and 4.5

Represents a chart area on the chart image.

Namespace:  System.Web.UI.DataVisualization.Charting
Assembly:  System.Web.DataVisualization (in System.Web.DataVisualization.dll)

public class ChartArea : ChartNamedElement

The ChartArea type exposes the following members.

Public methodChartArea()Initializes a new instance of the ChartArea class.
Public methodChartArea(String)Initializes a new instance of the ChartArea class with the specified chart area name.

Public propertyAlignmentOrientationGets or sets the alignment orientation of a chart area.
Public propertyAlignmentStyleGets or sets the alignment style of the ChartArea.
Public propertyAlignWithChartAreaGets or sets the name of the ChartArea object to which this chart area should be aligned.
Public propertyArea3DStyleGets or sets a ChartArea3DStyle object, which is used to implement 3D for all series in a chart area.
Public propertyAxesGets or sets an array that represents all axes for a chart area.
Public propertyAxisXGets or sets an Axis object that represents the primary X-axis.
Public propertyAxisX2Gets or sets an Axis object that represents the secondary X-axis.
Public propertyAxisYGets or sets an Axis object that represents the primary Y-axis.
Public propertyAxisY2Gets or sets an Axis object that represents the secondary Y-axis.
Public propertyBackColorGets or sets the background color of a ChartArea object.
Public propertyBackGradientStyleGets or sets the orientation for the background gradient of a chart area, and also determines whether or not a gradient is used.
Public propertyBackHatchStyleGets or sets the hatching style of a ChartArea object.
Public propertyBackImageGets or sets the background image of a ChartArea object.
Public propertyBackImageAlignmentGets or sets the alignment of a ChartArea background image.
Public propertyBackImageTransparentColorGets or sets the color of a ChartArea object background image that will be drawn as transparent.
Public propertyBackImageWrapModeGets or sets the drawing mode for the background image of a ChartArea object.
Public propertyBackSecondaryColorGets or sets the secondary color for the background of a ChartArea object.
Public propertyBorderColorGets or sets the border color of a ChartArea object.
Public propertyBorderDashStyleGets or sets the border style of a ChartArea object.
Public propertyBorderWidthGets or sets the border width of a ChartArea object.
Public propertyInnerPlotPositionGets or sets an ElementPosition object, which defines the inner plot position of a chart area object.
Public propertyIsSameFontSizeForAllAxesGets or sets a flag that determines if the labels of the relevant chart area axes are of equal size.
Public propertyNameGets or sets the unique name of a ChartArea object. (Overrides ChartNamedElement.Name.)
Public propertyPositionGets or sets an ElementPosition object that defines the position of a ChartArea object within the Chart.
Public propertyShadowColorGets or sets the shadow color of a ChartArea object.
Public propertyShadowOffsetGets or sets the shadow offset, in pixels, of a ChartArea object.
Public propertyTagGets or sets an object associated with this chart element. (Inherited from ChartElement.)
Public propertyVisibleGets or sets a value that indicates if a chart area is visible.

Public methodDispose()Releases the resources used by the ChartElement. (Inherited from ChartElement.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the ChartArea class and optionally releases the managed resources. (Overrides ChartElement.Dispose(Boolean).)
Public methodEqualsDetermines whether the specified Object is equal to the current ChartElement. (Inherited from ChartElement.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns a hash function for a particular type. (Inherited from ChartElement.)
Public methodGetSeriesDepthReturns the depth of a Series in a chart area.
Public methodGetSeriesZPositionReturns the Z position of a series, which is useful for custom drawing.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRecalculateAxesScaleRecalculates the properties of the chart area after changes have been made to the chart in the Customize event.
Public methodToStringReturns a string that represents the current Object. (Inherited from ChartElement.)
Public methodTransformPointsApplies 3D transformations to an array of 3D points, which must be done before GDI+ drawing methods can be called.

Within any given chart, the inner plot position is the rectangular area, inside the x and y-axis lines, where the data points are drawn. The plot position is the rectangular area that encompasses the inner plot position, the tick marks, and the axis labels. The chart area is the rectangular area that encompasses the plot position, the tick marks, the axis labels and the axis titles on the chart.

A chart area is represented by a ChartArea class; ChartArea objects are stored in the ChartAreaCollection class.

The number of chart series that can be plotted in a chart area is unlimited.

A ChartArea object:

  • Uses one distinct inner plotting area.

  • Is used to plot one or more chart series.

  • Has primary and secondary x and y-axes, except for pie and doughnut chart types.

When you use Shape chart types, which includes pie, doughnut, funnel, pyramid, polar, and radar charts, the inner plotting position defines the size of the chart type shape. For example, when you increase the value of the InnerPlotPosition property on a pie chart, you will increase the radius of the pie shape.

For all other chart types, each chart area has two sets of X- and Y-axes, primary and secondary. To access properties related to these axes, use the AxisX, AxisX2, AxisY and AxisY2 properties. If you need to set a property that affects all axes on the chart, use the Axes property.

One or more series are associated with a chart area. The series has a ChartArea property that determines the chart area that each series belongs to. By default, the series is connected to the default chart area. To disable the display of a series, set the ChartArea property of that series to a zero-length string.

If another chart area is added to the chart, you can associate any series with the new chart area. In all Shape chart types, as well as bar and stacked bar chart types, each series must be plotted in a separate chart area. In all other chart types, multiple series can be combined in the same chart area.

A 3D chart is displayed on a chart area-by-chart area basis. You can use the Area3DStyle property to enable and customize your chart in 3D.

The chart area minimum and maximum will not be automatically recalculated if you add new data, so the chart will not automatically change axis sizes.  You can require the chart area to recalculate these values by using the RecalculateAxesScale method.

To align multiple chart areas vertically, set the AlignmentOrientation property. To align multiple chart areas horizontally, you must first position the chart areas using the Position property, and then set the AlignmentOrientation property to Horizontal.

To suppress the display of a series, set the Series property of that series to a zero-length string.

.NET Framework

Supported in: 4.6, 4.5, 4
