For a small number of variables, you can build the plot manually yourself: ggplot(test_data, aes(date)) + geom_line(aes(y = var0, colour = “var0”)) + geom_line(aes(y = var1, colour = “var1”))
Robust peak detection algorithm (using z-scores) I came up with an algorithm that works very well for these types of datasets. It is based on the principle of dispersion: if a new datapoint is a given x number of standard deviations away from some moving mean, the algorithm signals (also called z-score). The algorithm is … Read more
