CCurve

The CCurve class works with the properties of the curves generated on the chart.

Description

The CCurve class sets, installs and receives the coordinates and various properties of the curves when working with the CGraphic class.

There are three curve plotting modes: dots, lines and histogram. Separate parameters are implemented for each plotting mode in the class.

Declaration

class CCurve : public CObject
