Functions

void chart_drawAxis (Bitmap *bm)
 Draw the chart axes.
void chart_drawCurve (Bitmap *bm, const chart_y_t *curve_y, int curve_cnt)
 Draw a set of curve_cnt connected segments, whose Y coordinates are identified by the curve_y array and X-coordinates are are evenly spaced by one virtual unit.
void chart_drawDots (Bitmap *bm, const chart_x_t *dots_x, const chart_y_t *dots_y, int cnt)
 Disegna dei dot in corrispondenza delle coppie (dotsx[i];dotsy[i]) Se dotsx e' NULL, i punti vengono disegnati ad intervalli regolari.

Width/height of the small ticks drawn over the axes

#define TICKS_HEIGHT   2
#define TICKS_WIDTH   2

Chart frame dimensions

#define CHART_BORDERTOP   0
#define CHART_BORDERBOTTOM   0
#define CHART_BORDERLEFT   0
#define CHART_BORDERRIGHT   0

Detailed Description

Simple charts on top of mware/gfx routines (interface).

Configuration:

Sample usage:

    bm = chart_init(0, ymax, N_POINTS_CURVE, ymin);

    chart_drawCurve(bm, curve_y, curve_points + 1);
    gfx_setViewRect(bm, xmin, ymax, xmax, ymin);
    chart_drawDots(bm, samples_x, samples_y, samples_cnt);

    print_bitmap(bm);
