Syntax:

property Min: Double

Applies to:
DMAxis, DMFloatEdit, DMSerie, DMSpinEdit

For DMAxis, Min define minimal value of the axis range. Note: if you want to fix axis range you have to clear AutoScale flag. Also keep in mind that in DM2003 Min may be greater than Max.

For DMSerie, this property allows you to change minimal limit of the parameter ("cx") for parameterized (or functional) series.

For DMSpinEdit and DMFloatEdit ActiveX controls, it defines minimal possible value of the Value property.

Syntax:

property Max: Double

Applies to:
DMAxis, DMFloatEdit, DMSerie, DMSpinEdit

For DMAxis, Max defines maximal value of the axis range. Note: if you want to fix axis range you have to clear AutoScale flag. Also keep in mind that in DM2003 Min may be greater than Max.

For DMSerie, this property allows you to change maximal limit of the parameter ("cx") for parameterized (or functional) series.

For DMSpinEdit and DMFloatEdit ActiveX controls, it defines maximal possible value of the Value property.

Syntax:

property Margins: Double

Applies to:
DMAxis

Margins defines the distance between axis ranges given by Min, Max values and calculated by series data. Value of 0.1 corresponds to approximately 10% blank space. This property should be used in conjunction with AutoScale.

Syntax:

property AutoScale: Boolean

Applies to:
DMAxis

If this flag set to true, every time when plot will be repainted new axis range will be automatically calculated. All nonempty series take part in autoscaling.

Syntax:

property Title: BSTR

Applies to:
DMAxis

Axis may have a title. If this property is not empty, axis title will be visible. Note that not all fonts are displayed properly in the vertical direction!

Syntax:

property Expression: BSTR

Applies to:
DMAxis, DMFitter

For DM2003 plot axis, you may transform all series simultaneously if you assign valid expression to this property. See details about expression syntax and allowed arguments and function names.

For DMFitter ActiveX control, Expression property should be defined before you start fitting. There are several possible situations:

• For predefined linear models possible values of this property are listed in the LinearBasisType Enumeration;
• You can define arbitrary linear basis if you assign to this property a string expression composed from basis members (expressions dependent only on CX parameter) divided by vbCrLf delimiter (see TestLinearGFit.htm demo for details);
• If you assign -1 (or True) to this property, DMFitter will invoke OnGetLinearBasis event handler to calculate user-defined basis members (see TestLinearEFit.htm demo);
  
  
• For LM fitter you can provide DM2003-compatible string expression (see details about expression syntax); in addition, the components of multidimensional independent variable are denoted by "cx1", "cx2", .. "cx25".
• Also you can define custom LM fitting object (see TestFitObject.htm demo for more information);
• If you assign -1 (or True) to this property, LM fitter will rely on OnGetLMFunction and OnGetLMDerivative event handlers to obtain values of function and partial derivatives. Value of -2 instructs LM fitter to invoke only OnGetLMFunction event and perform differentiation numerically (see TestLMFitEvents.htm and TestLMFitEJS.htm examples).
