While I agree with you that few users probably have experience with Scilab and the like, I don’t think that this is a problem or mooshis “fault”.

The mooshimeter is a multimeter and a data logger.
For the multimeter you need the device, the firmware and the app.
For the datalogger you need the device and the firmware – and that’s it.

There is no data logger in the world which take the task of you to evaluate and visualize the data for you.

So if someone is logging data he should bear in mind, that he himself needs to find a solution for evaluating that data.
