9 * \brief Simple charts on top of mware/gfx routines (interface).
12 * - \c CONFIG_CHART_TYPE_X: type for the input dataset of X-coordinates
13 * - \c CONFIG_CHART_TYPE_Y: type for the input dataset of Y-coordinates
16 * \author Bernardo Innocenti <bernie@develer.com>
21 *#* Revision 1.5 2004/09/14 20:56:39 bernie
22 *#* Make more generic and adapt to new gfx functions.
24 *#* Revision 1.3 2004/08/11 19:39:12 bernie
25 *#* Use chart_x_t and chart_y_t for the input dataset.
27 *#* Revision 1.1 2004/08/04 03:16:30 bernie
28 *#* Import simple chart drawing code.
