Remarks

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.

Constructors

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

Properties

AlignmentStyle	Gets or sets the alignment style of the ChartArea.
AlignWithChartArea	Gets or sets the name of the ChartArea object to which this chart area should be aligned.
Area3DStyle	Gets or sets a ChartArea3DStyle object, which is used to implement three-dimensional (3D) for all series in a chart area.
Axes	Gets or sets an array that represents all axes for a chart area.
AxisX	Gets or sets an Axis object that represents the primary X-axis.
AxisX2	Gets or sets an Axis object that represents the secondary X-axis.
AxisY	Gets or sets an Axis object that represents the primary Y-axis.
AxisY2	Gets or sets an Axis object that represents the secondary Y-axis.
BackColor	Gets or sets the background color of a ChartArea object.
BackGradientStyle	Gets or sets the orientation for the background gradient of a chart area, and also determines whether or not a gradient is used.
BackHatchStyle	Gets or sets the hatching style of a ChartArea object.
BackImage	Gets or sets the background image of a ChartArea object.
BackImageAlignment	Gets or sets the alignment of a ChartArea background image.

BorderWidth	Gets or sets the border width of a ChartArea object.
CursorX	Gets or sets a Cursor object that is used for cursors and selected ranges along the X-axis.
CursorY	Gets or sets a Cursor object that is used for cursors and selected ranges along the Y-axis.
InnerPlotPosition	Gets or sets an ElementPosition object, which defines the inner plot position of a chart area object.
IsSameFontSizeForAllAxes	Gets or sets a flag that determines if the labels of the relevant chart area axes are of equal size.
Name	Gets or sets the unique name of a ChartArea object.
Position	Gets or sets an ElementPosition object that defines the position of a ChartArea object within the Chart.
ShadowColor	Gets or sets the shadow color of a ChartArea object.
ShadowOffset	Gets or sets the shadow offset, in pixels, of a ChartArea object.
Tag	Gets or sets an object associated with this chart element. (Inherited from ChartElement)
Visible	Gets or sets a flag that determines if a chart area is visible.

Methods
