Linear Interpolation

This analysis object allows you to perform linear interpolation for your data. During linear interpolation, the points of the original data set are connected using straight lines. The resulting, continuous curve will then be sampled at the points specified.

You can specify here that the result is to have the same number of values as the data set to be interpolated or you can specify a new number of values. In any case, the result is equidistantly sampled, meaning that neighboring X values are at the same distance. Thus, linear interpolation is frequently used to transform non-equidistantly sampled data series into equidistantly sampled data series.
