* Processes data from a data series to complete the data holes with a fill value.
|
|
|

|
|
|
* A data hole is determined by the resolution passed in parameter: if, between two continuous
|
|
|
* data on the x-axis, the difference between these data is greater than the resolution, then
|
|
|
* there is one or more holes between them. The holes are filled by adding:
|
|
|
* - for the x-axis, new data corresponding to the 'step resolution' starting from the first
|
|
|
* data;
|
|
|
* - for values, a default value (fill value) for each new data added on the x-axis.
|
|
|
*
|
|
|
* For example, with :
|
|
|
* - xAxisData = [0, 1, 5, 7, 14 ]
|
|
|
* - valuesData = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] (two components per x-axis data)
|
|
|
* - fillValue = NaN
|
|
|
* - and resolution = 2;
|
|
|
*
|
|
|
* For the x axis, we calculate as data holes: [3, 9, 11, 13]. These holes are added to the
|
|
|
* x-axis data, and NaNs (two per x-axis data) are added to the values:
|
|
|
* => xAxisData = [0, 1, 3, 5, 7, 9, 11, 13, 14 ]
|
|
|
* => valuesData = [0, 1, 2, 3, NaN, NaN, 4, 5, 6, 7, NaN, NaN, NaN, NaN, NaN, NaN, 8, 9]
|
|
|
*
|
|
|
* @param xAxisData the x-axis data of the data series
|
|
|
* @param valuesData the values data of the data series
|
|
|
* @param resolution the resoultion (on x-axis) used to determinate data holes
|
|
|
* @param fillValue the fill value used for data holes in the values data
|
|
|
*
|
|
|
* @remarks There is no control over the consistency between x-axis data and values data. The
|
|
|
* method considers that the data is well formed (the total number of values data is a multiple
|
|
|
* of the number of x-axis data)
