SYNOPSIS

#include <agar/core.h>
#include <agar/gui.h>

DESCRIPTION

AG_FixedPlotter traces lines or dots over recorded integer values along a horizontal axis. Originally designed to monitor frame rates, it can be useful for performance monitoring in general.

Note: For general-purpose and more advanced plotting functions, M_Plotter(3) is available as part of the ag_math library.

INHERITANCE HIERARCHY ↑

AG_Object(3)-> AG_Widget(3)-> AG_FixedPlotter.

INITIALIZATION ↑

AG_FixedPlotter * AG_FixedPlotterNew (AG_Widget *parent, enum ag_fixed_plotter_type type, Uint flags)

The AG_FixedPlotterNew() function allocates, initializes, and attaches a new AG_FixedPlotter widget. The type argument is one of:

enum ag_fixed_plotter_type {
	AG_FIXED_PLOTTER_POINTS,   /* Dots */
	AG_FIXED_PLOTTER_LINES     /* Lines */
} type;

Acceptable flags include:

AG_FIXED_PLOTTER_SCROLL	Always scroll to the end of the plot if it is not visible.
AG_FIXED_PLOTTER_XAXIS	Display the X-axis line.
AG_FIXED_PLOTTER_HFILL	Expand horizontally in parent container.
AG_FIXED_PLOTTER_VFILL	Expand vertically in parent container.
AG_FIXED_PLOTTER_EXPAND	Shorthand for AG_FIXED_PLOTTER_HFILL AG_FIXED_PLOTTER_VFILL\|.

PLOTTING ↑

AG_FixedPlotterCurve * AG_FixedPlotterCurve (AG_FixedPlotter *fpl, const char *name, Uint8 r, Uint8 g, Uint8 b, Uint32 limit)

void AG_FixedPlotterDatum (AG_FixedPlotterCurve *curve, AG_FixedPlotterValue val)

The AG_FixedPlotterCurve() function creates a new curve into fpl. The r, g, b triplet composes a color to visually identify the item. limit is the maximum number of points (if 0, the maximum is implicitely INT_MAX - 1).

The AG_FixedPlotterDatum() function adds a value val to the specified curve.

EVENTS ↑

The AG_FixedPlotter widget does not generate any event.

STRUCTURE DATA ↑

For the AG_FixedPlotter object:

enum ag_fixed_plotter_type type

Drawing method, initially set by AG_FixedPlotterNew().

HISTORY ↑

The AG_FixedPlotter widget first appeared in Agar 1.0.
