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 1.3 2004/08/11 19:39:12 bernie
22 * Use chart_x_t and chart_y_t for the input dataset.
24 * Revision 1.1 2004/08/04 03:16:30 bernie
25 * Import simple chart drawing code.
