    I want to do an XY display of two datasets with different sampling rates. How can I adjust the datasets to each other so that they have the same length?

    There is a function Sample available in FPScript which can be used to re-sample a dataset. A formula to create a Dataset for XY-display could look like this:

    
Signal(Dataset1, Sample(Dataset2, Diataset1.x))

    The formula above should be used only, if the X range of Dataset2 exceeds that of Dataset1. If the opposite is the case, then the formula should be:

    
Signal(Sample(Dataset1, Dataset2.x), Dataset2)
