35 * It is also possible to set bounds for the data series. If these bounds are defined and exceed
36 * the limits of the data series, data holes are added to the series at the beginning and/or the
37 * end.
38 *
39 * The generation of data holes at the beginning/end of the data series is performed starting
40 * from the x-axis series limit and adding data holes at each 'resolution step' as long as the
41 * new bound is not reached.
42 *
43 * For example, with :
44 * - xAxisData = [3, 4, 5, 6, 7 ]
45 * - valuesData = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
46 * - fillValue = NaN
47 * - minBound = 0
48 * - maxBound = 12
49 * - and resolution = 2;
50 *
51 * => Starting from 3 and decreasing 2 by 2 until reaching 0 : a data hole at value 1 will be
52 * added to the beginning of the series
53 * => Starting from 7 and increasing 2 by 2 until reaching 12 : data holes at values 9 and 11
54 * will be added to the end of the series
55 *
56 * So :
57 * => xAxisData = [1, 3, 4, 5, 6, 7, 9, 11 ]
58 * => valuesData = [NaN, NaN, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, NaN, NaN, NaN, NaN]

60 * @param xAxisData the x-axis data of the data series
36 * @param valuesData the values data of the data series
