class SRGDecimalScale
Derived from SRGraphLabelBlock, this class manages a decimal numeric scale placed between two screen point positions. The scale will automatically calculate the best possible sequence of numbers depending upon the length of the line and the size of the font.
Defined in: DScale.h
CHART_API virtual CPoint GetRelOffset()
Get the relative offset of the labels from the DC origin
CHART_API virtual CPoint GetOffset()
Get the offset of the labels from the tick list
BOOL m_bAscending
TRUE when the list of numerals generated is to go from low values toward high values
CPoint m_ptStart
Start position of the line of numerals
CPoint m_ptEnd
End position of the line of numerals
double m_dMinValue
Minimum value in the range of generated numbers
double m_dMaxValue
Maximum value in the range of generated numbers
double m_dResolution
Preferred or initial resolution of steps in the number list
CString m_strFormatString
Format string used to generate the numeral strings (see sprintf)
BOOL m_bLabelSide
Side of the imaginary line between m_ptStart and m_ptEnd on which labels are displayed -- FALSE=left/below, TRUE=right/above
CHART_API virtual void Serialize(CArchive &ar)
Writes or restores the scale to an archive for reuse
