Scale

Remark

The Scale class provides methods and properties common to all Origin axis scales. Two scale objects (one X scale and one Y scale) are contained in each graph layer on each graph page.

An Origin C Scale object is a wrapper object that is a reference to an internal Origin scale object. Origin C wrapper objects do not actually exist in Origin and merely refer to the internal Origin object. Consequently, multiple Origin C wrapper objects can refer to the same internal Origin object.

The Scale class is derived from the OriginObject class from which it inherits methods and properties.

Examples

EX1

void Scale_ex1()
{
    GraphPage gp;
    gp.Create("origin");
    GraphLayer    gl(gp.GetName(),0);
    if(gl)                                  // If valid graph layer...
    {
        Scale sc(gl.X);                     // Get X scale object from graph layer
        sc.From = 0.01;                     // Assign scale from value
        sc.To = 1000;                       // assign scale to value
        sc.Type = LOG10_SPACE;              // Set axis scale as Log10
        sc.Inc = 1;                         // set axis scale increment to 1
    }
}

Members

Name Brief Example
Scale Default constructor which constructs an unattached Scale object. The member function IsValid() of the base class OriginObject can be used to determine if the object is valid (attached to an internal Origin axis) Examples

Property

Name Brief Example
From The "From" property - the left limit of the axis Examples
Inc The "Inc" property - the major tick increment of the axis Examples
Rescale The "Rescale" property - Rescale Type Examples
To The "To" property - the right limit of the axis Examples
Type The "Type" property - the axis type. Examples
