DESCRIPTION

EZDDiag creates a diagram as an ezd object. Actually there are three different styles (as an enum) implemeted in this class:

• DOT : draws the diagram in form of dots
• LINE : draws a line
• HISTO: draws a histogram

Constructors:

EZDDiag();

EZDDiag(CNParam *param)

EZDDiag(int w, int h, Style s=LINE);

EZDDiag(int w, int h, int x, int y, Style s=LINE);

EZDDiag(const CNString &name, int w, int h, int x, int y, Style s=LINE);

EZDDiag(int w, int h, int x, int y, Style s, CNString cd, CNString cb);

EZDDiag(const CNString &name, int w, int h, int x, int y, Style s, CNString cd, CNString cb);

Initializes EZDDiag at the position (x,y), default (0,0), of the current drawing as a named ezd object. w (default: 200) and h (100) are the object`s width and heigth. cd ("black") and cb ("red") are color-settings for the diagram and the bar which is drawn if the value is out of the given range - e.g. negative values or values > 100 at the default setting. The possible styles s are described above. The object is drawn frameless, but a frame can be added, see the functions below.

In addition to the member functions required by CNCL, EZDDiag provides:

void style(Style s);

Sets the style of the diagram to s.

void set_color_draw(CNString c);

Sets the drawing color to c.

void set_color_bar(CNString c);

Sets the color of the bar (out-of-range display) to c.

void add(int v);

Adds the value v to the diagram.

void clear();

Clears the diagram.

virtual void redraw();

Redraws the diagram.

void set_frame();

Sets a frame to the diagram.
