Interpolate data in stream

[fmanniti]

Is there a easy/fast way to interpolate all data in a stream?

I would like, given a startDate and endDate and a step, a stream with timestamps every step, and values the interpolation of the original data.

My stream:

timestap	value
2017-10-27 15:13:25.123	557
2017-10-27 17:19:11.024	678
2017-10-27 20:02:34.987	558
2017-10-27 23:45:13.356	547
2017-10-28 02:12:56.223	447
2017-10-28 03:27:16.133	469

I would like this result:

timestap	value
2017-10-27 16:00	576,53
2017-10-27 18:00	626,85
2017-10-27 20:00	679.08
2017-10-27 22:00	614.50
2017-10-28 00:00	664.63
2017-10-28 02:00	655.65

where values come from the interpolation formula

v* = v_0 +[(v_1 - v_0 ) / (t_1 - t_0)]*(t* - t_0)

I tried the service "Interpolate" but doesn't seem to work.

Thank you

This is how I used Interpolate function

(start and end are given as input)

var propertyColumn = "Strain_Measure_Current";
var queryOnStream = {"filters":{"type":"LIKE","fieldName":propertyColumn,"
var streamFiltered = me.QueryStreamEntriesWithData({oldestFirst: true, query: queryOnStream});
var params = {
    mode: 'ROWCOUNT',
    timeColumn: 'timestamp',
    t: streamFiltered,
    stats: 'SMOOTH',
    endDate: end,
    columns: propertyColumn,
    count: 50,
    startDate: start
};
result = Resources["InfoTableFunctions"].Interpolate(params);

I get this error

java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double - 17
