Properties

Interval

Gets or sets a value that determines the interval between labels. Its nullable. If this property is not set, interval will be calculated automatically.

Declaration
public double? Interval { get; set; }
Property Value
Type
System.Nullable<System.Double>

LogarithmicBase

Gets or sets the base for the LogarithmicAxis.

Declaration
public double LogarithmicBase { get; set; }
Property Value
Type Description
System.Double

2 for binary logarithm, 10 for common logarithm.

Maximum

Gets or sets the maximum value for the axis range. This is nullable property.

Declaration
public double? Maximum { get; set; }
Property Value
Type
System.Nullable<System.Double>
Remarks

If we didn't set the maximum value, it will be calculate from the underlying collection.

Minimum

Gets or sets the minimum value for the axis range. This is nullable property.

Declaration
public double? Minimum { get; set; }
Property Value
Type
System.Nullable<System.Double>
Remarks

If we didn't set the minimum value, it will be calculate from the underlying collection.
