class Plot

Represents a set of data series in PlotData format together with information how to display them.

Plot& SetLimits(const Rectf& rect)

Plot& SetLimits(double x_min,double x_max,double y_min,double y_max)

Sets the area to be displayed.

Plot& SetFont(const Font& font)

Sets font to be used.

Plot& SetBackground(const Color& c)

Sets background color.

Plot& SetFrameColor(const Color& c)

Sets color of the frame.

Plot& SetFontColor(const Color& c)

Sets font color.

Plot& SetAxisColor(const Color& c)

Sets color of axis.

Plot& SetMode(int quality)

Sets quality of the rendering. Available values are:

Plot& SetPlotSize(double cx,double cy)
