/**
 * Adds the main data set for all times and the data set for the progression of record best
 * times among all times. The progression of best times are marked in a different color to the
 * main line of all time using circles lined with a dashed line. This will appear to connect
 * the lowest troughs along the main line of all times.
 *
 * @param chartData The chart data to which to add the new data sets.
 * @param allLabel  The label of the all-times line.
 * @param allColor  The color of the all-times line.
 * @param bestLabel The label of the best-times line.
 * @param bestColor The color of the best-times line.
