Function plot_add_series

plot/plot.c:428–478

* @brief Append a new series of any drawing style to the plot. * * Allocates internal buffers and deep-copies @p xData (if non-NULL), * @p yData, and @p label into them. The series is stored in the next * free slot of the plot's fixed-capacity series table and given the * supplied colour and drawing style. * * If @p xData is NULL the renderer falls back to using the implicit * indices 0..d

 * @endcode
