Several years ago, @JeroenMulkers created the
FunctionFromDatafilefunction. This can be used to read a CSV file and create a function that maps any column to another column. I now added a test for this, and the feature can be merged.The function is used as
FunctionFromDatafile(filename, xColumnIdx, yColumnIdx, interpolation), where the available interpolation methods are the self-explanatory"linear","nearest"or"step". Example usage:where the first column of
data.csv(i.e. column index 0) in this example contains the timestamps, and the second column (index 1) contains the field magnitudes. Lines indata.csvstarting with#are ignored, so can be used for e.g. a header row.
