Example

This example shows how to use NumericScaleOptions to reduce the number of visible series points.

The following code configures the axis scale settings to resemble to the chart appearance above:

C#

NumericScaleOptions numericScaleOptions = ((XYDiagram)chartControl.Diagram).AxisX.NumericScaleOptions;

numericScaleOptions.ScaleMode = ScaleMode.Manual;
numericScaleOptions.MeasureUnit = NumericMeasureUnit.Hundreds;
numericScaleOptions.GridOffset = 5;
numericScaleOptions.AggregateFunction = AggregateFunction.Average;
numericScaleOptions.GridAlignment = NumericGridAlignment.Thousands;
numericScaleOptions.GridSpacing = 1;

VB.NET

Dim numericScaleOptions As NumericScaleOptions = CType(chartControl.Diagram,XYDiagram).AxisX.NumericScaleOptions

numericScaleOptions.ScaleMode = ScaleMode.Manual
numericScaleOptions.MeasureUnit = NumericMeasureUnit.Hundreds
numericScaleOptions.GridOffset = 5
numericScaleOptions.AggregateFunction = AggregateFunction.Average
numericScaleOptions.GridAlignment = NumericGridAlignment.Thousands
numericScaleOptions.GridSpacing = 1

The following table lists the API members the code above uses:

NumericMeasureUnit	Lists the values that specify the detail level for numeric values.
ScaleGridOptionsBase.GridOffset	Gets or sets the offset of grid lines and major tickmarks.
ScaleGridOptionsBase.AggregateFunction	Gets or sets the value indicating the aggregate function that should be used to relieve data.
AggregateFunction	Lists the values that specify the aggregate function used for an axis.
NumericScaleOptions.GridAlignment	Gets or sets the numeric measure unit to which the beginning of an axis’ gridlines and labels should be aligned.
NumericGridAlignment	Lists the values that specify the numeric-time measurement unit, to which the beginning of a diagram’s gridlines and labels should be aligned.
ScaleGridOptionsBase.GridSpacing	Gets or sets the interval between grid lines and major tickmarks.
